Best Air Purifier Australia 2026 — Tested & Compared

If you've just moved into a new home, the air inside it might not be as clean as you think. New paint, carpet, furniture, and building materials release volatile organic compounds (VOCs) for months after construction. Add in dust mites, pet dander, pollen from the garden, and the seasonal threat of bushfire smoke, and indoor air quality becomes something worth thinking about — particularly if anyone in your household has allergies, asthma, or a newborn.

Air purifiers have gone from niche health products to mainstream home appliances in Australia, driven largely by the 2019-2020 bushfire season and growing awareness of indoor air quality. For new homeowners, particularly those with babies, young children, or allergy sufferers, a quality HEPA air purifier is one of the higher-return health investments you can make.

We've reviewed the major air purifier brands available on Amazon Australia for 2026 and verified each pick via the Amazon Creators API on the day of publication. Every machine on this list is in stock with a confirmed buy-box at the time you're reading this.

TL;DR — Best Air Purifiers Australia 2026

Last updated June 2026. Six picks across budget, mid-range and large-room tiers — every machine verified in stock on Amazon AU on the day of publication.

• Best overall: Coway Airmega Mighty AP-1512HH at ~$269 — New York Times top pick, True HEPA + activated carbon, 109m² coverage, 4.6 stars across 284 AU ratings.
• Best for large rooms: Coway Airmega 250 (AP-1720H) at ~$419 — 131m² coverage, HyperCaptive + True HEPA double filtration, Smart Mode, Sensitive Choice asthma-certified.
• Best budget: Levoit Core Mini at ~$80 — compact 3-in-1 True HEPA desktop unit, 25dB ultra-quiet, built-in night light, perfect for a desk or small bedroom.
• Best set-and-forget — 5-year filter: Shark NeverChange Compact Pro at ~$179 — filter lasts 5 years, lowest ongoing cost on the list.
• Best asthma/allergy pick: Coway Airmega 150 (AP-1019C) at ~$209 — Sensitive Choice asthma-certified, triple-layer True HEPA filtration, 73m² coverage, 20dB Quiet Mark sleep mode.
• Best ultra-quiet larger-room: Philips 1000i Series (AU SKU for the EU AC1715) at ~$199 — 78m² coverage, 300 m³/h CADR, smart sensor + app.

About this list. Australian shoppers often look for IQAir HealthPro, Molekule Air Pro, or AirDoctor Pro 5000 air purifiers — these premium specialty brands are sold predominantly via specialty health and allergy retailers (Air Purifiers Direct, IQAir Australia, breathesafe.com.au) rather than Amazon AU. The picks below optimize for what Amazon AU does well: True HEPA purifiers from broad-distribution brands (Coway, Levoit, Shark, Philips) with reliable buy-box presence and same-day Prime delivery in metro areas. Coway appears three times because it carries the deepest verified review counts on Amazon AU in this category, and two of its models hold Sensitive Choice certification from the National Asthma Council Australia — the trust signal that matters most for asthma and allergy households.

Best overall — Coway Airmega Mighty AP-1512HH, ~$269

The Coway Airmega Mighty AP-1512HH is the best air purifier on this list for most Australian homes. It's the model the New York Times has named a top air purifier, and on Amazon AU it carries the deepest review base in this guide — 4.6 stars across 284 ratings, with an Amazon's Choice badge. At ~$269 it sits in the value sweet spot: True HEPA plus an activated-carbon stack that removes 99.999% of airborne particles and pollutants, an eco mode with a real-time air-quality LED that powers the unit down when the air is clean, and coverage up to 109m² — comfortably handling most living rooms or open-plan kitchen-dining areas.

The four-stage stack (pre-filter, deodorising carbon, True HEPA, plus a switchable ioniser) handles the full range of indoor pollutants: PM2.5 from bushfire smoke, pollen, pet dander, dust-mite droppings, and odours and VOCs from new paint and furniture. The integrated air-quality sensor drives an automatic mode that ramps the fan up when particles spike and eases it back down when the air clears, so you can leave it running 24/7 without thinking about it.

Why we keep the ioniser switched off: at consumer fan speeds the ioniser produces trace amounts of ozone, which is itself a pulmonary irritant. The HEPA + carbon + pre-filter stack does all the real work; the ioniser is at best redundant and at worst counter-productive for asthma sufferers. Leave it off and you lose nothing.

• Pros: New York Times top pick with the deepest AU review count on this list (4.6 stars, 284 ratings, Amazon's Choice), True HEPA + activated carbon removes 99.999% of particles and pollutants, 109m² coverage, eco mode with real-time air-quality LED, replacement filters $50-80 (cheaper than premium brands).
• Cons: No smart-home integration (no Wi-Fi/app), slightly dated industrial design (white plastic shell), ioniser feature is best left off.
• Flaws: The carbon filter has a shorter life than the HEPA — it needs replacing roughly every 6 months at typical urban Australian usage versus the HEPA's 12-month interval. The filter-life indicator needs a manual reset after each replacement.
• Best for: Living rooms and open-plan areas where you want reliable, low-fuss purification without app complexity, on a value-conscious budget — the default recommendation for most first-home buyers.

Best for large rooms — Coway Airmega 250 (AP-1720H), ~$419

If your space is bigger than the Mighty was built for — a large open-plan living area, a 130m²-class room, or a whole-of-floor setup — the Coway Airmega 250 is the step up. It cleans up to 131m² (and clears a 52m² room in around 15 minutes), and pairs a HyperCaptive filter with a True HEPA stage for double filtration that removes 99.999% of pollutants right down to 0.01 microns. On Amazon AU it holds 4.8 stars across 26 ratings, an Amazon's Choice badge, and ranks #14 in Air Purifiers.

The headline feature for households with allergy or asthma concerns is the certification: the Airmega 250 is Sensitive Choice Certified for Asthma & Allergies by the National Asthma Council Australia — an independent Australian trust mark that the cheaper budget units don't carry. A Smart Mode auto-adjusts the fan to live air quality, and a 1/4/8-hour timer lets you set it and walk away.

You pay more than the Mighty for the larger coverage, the double-filtration HyperCaptive stage, and the Smart Mode automation. If your main room is well under 100m², the Mighty above is the better-value buy; step up to the 250 when the room genuinely demands the extra capacity or you specifically want the Sensitive Choice certification on a large-room machine.

• Pros: 131m² coverage (clears a 52m² room in ~15 minutes), HyperCaptive + True HEPA double filtration removes 99.999% of pollutants to 0.01 microns, Sensitive Choice Certified for Asthma & Allergies, Smart Mode auto-adjusts to air quality, 1/4/8-hour timer, highest star rating on the list (4.8 stars), Amazon's Choice.
• Cons: Highest price on the list (~$419), thinner review base than the Mighty (26 ratings vs 284), no Wi-Fi app — automation is on-device only.
• Flaws: Overkill for a bedroom or small home office, where the running cost and footprint outweigh the coverage benefit. The smaller review count means less long-run reliability data than the long-established Mighty.
• Best for: Large open-plan living areas and 100m²-plus rooms, and asthma/allergy households that want Sensitive Choice certification on a large-room machine.

Best budget — Levoit Core Mini, ~$80

The Levoit Core Mini is the pick when you want genuine True HEPA filtration without spending much, and you're treating a small space rather than a whole living room. It's a compact desktop/personal unit — small enough to sit on a desk, a bedside table, or a shelf — built around a 3-in-1 True HEPA plus activated-carbon filter that handles smoke, odours, allergens, dust and pet dander. On Amazon AU it's an Amazon's Choice pick at 4.5 stars across 439 ratings.

For a unit this size it punches above its price. It runs at an ultra-quiet 25dB — quiet enough to leave on overnight beside a bed — draws just 7W (about 36 cents of electricity a week to run), and adds a built-in night light plus an optional aromatherapy pad. There's no app and no air-quality sensor at this tier; you set the fan speed manually and let it run.

Be honest with yourself about coverage: this is a small-space purifier, not a whole-room one. It's ideal for a desk, a study nook, a nursery, or a small bedroom. If you need to clean a living room or an open-plan area, step up to the Coway Airmega Mighty at the top of this list or the Airmega 250 for larger spaces — the Core Mini will be out of its depth in those rooms.

• Pros: Genuine 3-in-1 True HEPA + activated-carbon filtration at ~$80, ultra-quiet 25dB, very cheap to run (7W, ~36 cents a week), built-in night light, optional aromatherapy pad, Amazon's Choice with 439 AU ratings.
• Cons: Small-space coverage only — not a whole-room unit, no Wi-Fi app, no air-quality sensor or auto mode (manual fan speed only).
• Flaws: The compact filter saturates faster than full-size purifier filters if you run it in a dusty or smoky room, so plan on more frequent replacements in heavy-use conditions. Without an auto mode you have to remember to step the fan up yourself when air quality drops.
• Best for: Desks, study nooks, nurseries and small bedrooms — and as a first air purifier for someone testing whether HEPA filtration helps their allergies before committing to a larger unit.

Best set-and-forget — Shark NeverChange Air Purifier Compact Pro, ~$179

The Shark NeverChange is the pick for buyers who don't want to think about filter replacement for half a decade. Shark's marketing claim is in the product name: the filter lasts 5 years. The engineering trade-off is a physically larger, denser filter stack that uses HEPA-exceeding pleated media — captures 99.97% of particles at 0.3 microns, same as H13 HEPA, but with extended service life.

At $179 it's the cheapest pick on this list — and the lowest 5-year total cost of ownership of any HEPA purifier on the AU market. A typical air purifier needs $40-$130 of filter replacements per year. The NeverChange Compact Pro needs zero filter replacements through year 5. That's $200-$650 in saved filter costs across the ownership period.

Trade-off: rated coverage is only 23m². This is firmly a single-room purifier — bedroom, nursery, or small home office. Don't try to use it for an open-plan living area; you'd need two or three of them to keep up.

• Pros: 5-year filter life (no replacements through year 5), lowest total-cost-of-ownership on the list, HEPA-exceeding 99.97% particle capture, $179 entry price, compact footprint.
• Cons: 23m² coverage limits it to single small rooms, no Wi-Fi/app control, no air-quality sensor (no auto mode — manual fan speed only), large filter unit makes the device taller than it looks in photos.
• Flaws: The "5-year filter" claim assumes typical urban Australian usage and clean ambient conditions. If you live near a busy road, have multiple pets, or run it during bushfire smoke events for sustained periods, filter life will be materially shorter (Shark estimates 2-3 years in those conditions). Filter replacement when needed is a $120+ part.
• Best for: Bedroom or nursery buyers who prioritise zero ongoing maintenance over coverage area or smart features. Renters who want lifecycle simplicity.

Best asthma/allergy pick — Coway Airmega 150 (AP-1019C), ~$209

The Coway Airmega 150 is the pick if asthma or allergies are the reason you're buying a purifier at all. It's Sensitive Choice Certified for Asthma & Allergies by the National Asthma Council Australia — the same independent Australian trust mark the larger Airmega 250 carries — and at ~$209 it's the more affordable way into that certification. On Amazon AU it's an Amazon's Choice pick at 4.7 stars across 287 ratings and ranks #7 in Air Purifiers.

Filtration is a triple-layer stack: a pre-filter, a deodorisation layer, and a True HEPA stage that removes 99.999% of allergens down to 0.01 microns. Coverage is up to 73m² — enough for a bedroom, a study, or a medium living area. It sits between the small-space Levoit Core Mini and the large-room Airmega 250 in capacity, while sharing the 250's Sensitive Choice certification.

Where the 150 really wins is overnight quiet: its Sleep Mode runs at 20dB and is Quiet Mark certified — quieter than almost anything else on this list, and low enough to leave running all night in a bedroom without notice. Coway brings 30-plus years of air-care engineering to it.

• Pros: Sensitive Choice Certified for Asthma & Allergies (National Asthma Council Australia), triple-layer True HEPA filtration removes 99.999% of allergens to 0.01 microns, 73m² coverage, 20dB Quiet Mark-certified Sleep Mode, 4.7 stars across 287 AU ratings, Amazon's Choice, #7 in Air Purifiers.
• Cons: No Wi-Fi app or smart-home integration, smaller coverage than the Airmega 250, plain plastic shell looks utilitarian next to the Philips.
• Flaws: Like the rest of the Airmega line it uses an on-device sensor and on-device controls only — there's no app history or remote control. The carbon/deodorisation layer saturates faster than the HEPA stage, so plan on replacing it ahead of the main filter in odour-heavy rooms.
• Best for: Asthma and allergy households on a mid-tier budget who want Sensitive Choice certification plus the quietest sleep mode on the list, for a bedroom or medium living area.

Best ultra-quiet larger-room — Philips 1000i Series Air Purifier (AC1715), ~$199

Philips 1000i Series is the Australian model name. International reviews often call it the AC1715 — same machine, different market badge. The "1000i" is Philips's AU naming convention for the i-Series; the AC1715/70 is the model number printed on the back of the unit. If you see either name in reviews or Amazon listings, you're looking at the same physical product.

The 1000i Series is the ultra-quiet large-room pick. 78m² coverage, 300 m³/h CADR, sleep mode that drops noise to 17dB — the quietest sleep-mode reading on this list (below the Coway Airmega 150's 20dB and the Levoit Core Mini's 25dB). NanoProtect HEPA filter media (Philips's proprietary spec, exceeds H13 standard) + activated carbon, smart sensor with real-time AQI on the unit's display, Wi-Fi app control, voice-assistant compatible.

Where the Philips wins versus the Coway Mighty: build quality (powder-coated steel chassis vs Coway's plastic), display (proper AQI numbers vs Coway's three-LED indicator), and noise floor (17dB vs Coway's 28dB sleep). Where it loses: coverage area (78m² vs 109m²) and replacement filter cost ($85 every 12 months vs Coway's $50-60).

• Pros: Quietest sleep mode on the list (17dB), premium build quality with steel chassis, real-time AQI display, Wi-Fi app + voice assistant support, NanoProtect HEPA exceeds H13 standard, 78m² coverage suitable for medium living rooms or large bedrooms.
• Cons: Smaller coverage than the Coway Mighty, proprietary Philips filters ($85 every 12 months — more expensive than Coway), AU/EU model naming confusion (1000i vs AC1715).
• Flaws: The Air+ app requires a separate Philips account (can't merge with existing Hue lighting accounts). The smart-sensor calibration drifts over 6-12 months and needs manual reset via a button combination — not documented in the included quick-start guide.
• Best for: Buyers who want premium build quality + the quietest sleep mode at a mid-premium tier, particularly for medium bedrooms (15-30m²) where the 17dB floor matters.

Philips is a large global brand with broad Australian multi-retailer distribution. Standard framing. Note: AU model naming differs from EU — the 1000i Series in AU is the AC1715/70 in EU and the AC1715 in the US.

What to look for in an air purifier

The five decisions that actually matter when you're picking an air purifier:

HEPA grade — H13, "True HEPA", or "HEPA-type"

True HEPA (H13) captures 99.97% of particles down to 0.3 microns — the gold standard. Every pick on this list uses true HEPA. "HEPA-type" or "HEPA-like" filters capture 85-95% — sounds close but means 5-15x more particles pass through. Avoid anything that doesn't explicitly say "True HEPA" or "H13" on the spec sheet.

CADR and room coverage

CADR (Clean Air Delivery Rate, m³/h) measures how fast the purifier cleans air. Match CADR to your room size: bedroom (10-20m²) needs CADR 150+ m³/h; living room (20-40m²) needs 300+; open-plan (40m²+) needs 400+ or two smaller units. Rule of thumb: the purifier should cycle the room's air volume at least 4-5 times per hour. Manufacturer "rated coverage" numbers often assume 2 air changes per hour — divide by 2 for real-world equivalents.

Activated carbon — for VOCs, gases, odours

HEPA captures particles but doesn't capture gases. For new-home VOCs (the benzene and toluene that off-gas from fresh paint and furniture), cooking odours, pet smell, or smoke gases, you need a separate activated carbon stage. Every pick on this list pairs True HEPA with an activated-carbon layer — including the budget Levoit Core Mini, which uses a combined 3-in-1 True HEPA plus activated-carbon filter.

Pet-dander considerations

Pet households should prioritise three features: (1) higher CADR (250+ m³/h) to keep up with continuous shedding, (2) a washable mesh pre-filter to catch hair before it reaches the HEPA stage (cheap and extends HEPA life dramatically), and (3) an air-quality sensor with auto mode that ramps up during high-activity periods. Pet Mode (Levoit Vital 200S, some Shark models) automatically boosts fan speed during shedding periods — useful but not essential. The Coway Airmega Mighty, Airmega 250, and Airmega 150 all handle pet dander well at their respective price points, thanks to their pre-filter plus True HEPA stacks.

Noise floor — sleep-mode dB

The noise spec that matters is sleep-mode dB, not max-fan-speed dB. You'll run the purifier on sleep for 8 hours a night; you'll rarely hit max. The Philips 1000i (17dB), the Coway Airmega 150 (20dB, Quiet Mark certified) and the Levoit Core Mini (25dB) lead the list on sleep-mode quiet. Anything above 35dB sleep is too loud for a bedside table.

Care and maintenance

Air purifiers are low-maintenance but neglected filters cripple performance. Four habits:

Weekly — vacuum the pre-filter

The pre-filter catches large particles (hair, dust clumps) before they reach the HEPA. Use a handheld vacuum on the mesh side weekly. Takes 30 seconds and dramatically extends HEPA life. Almost no one does this; everyone should.

Monthly — clean the air-quality sensor

The air-quality sensor that drives auto and smart modes (Philips, Coway Airmega 250 and 150) accumulates dust on the optical surface and stops reading accurately over time. Most models have a small cover that pops off — wipe the sensor lens with a microfibre cloth monthly so auto mode keeps responding to real particle levels rather than a dusty reading.

Every 6-12 months — replace the HEPA filter

Most HEPA filters need replacement every 6-12 months depending on usage and air quality. Filter-life indicators are airflow-based on better models (Philips, the Coway Airmega line) and timer-based on cheaper or smaller models. Don't wash HEPA filters under any circumstances — water destroys the fibre structure permanently.

As needed — extra filter changes after smoke events

Bushfire smoke and renovation dust load filters fast. If you run your purifier through a multi-day smoke event or during home renovation work, plan on replacing the HEPA filter immediately afterward — even if the indicator hasn't tripped. The filter has absorbed months of particle load in a few days.

You'll also want — accessories

Five accessories that make any purifier on this list better:

• Spare HEPA filters: $40-$120 depending on brand. Keep one on the shelf so you can swap immediately when the indicator trips. Browse →
• Replacement Coway Airmega filters: $50-$80 depending on model. The Mighty, Airmega 250 and Airmega 150 each take a model-specific True HEPA + carbon set — keep a spare on the shelf so you can swap the moment the indicator trips. Browse →
• Indoor air quality monitor: $80-$200 for a standalone monitor (Awair Element, Temtop M10, Aranet4) that shows real-time PM2.5, CO₂, VOCs, humidity. Useful to verify your purifier is actually working in different rooms.
• Surge protector with on/off switch: $20-$40. Lets you remotely power-cycle the purifier (some models hang after Wi-Fi outages and only recover via power cycle).
• Wall-mount kit (Philips, Coway): $40-$80 brand-specific. Wall-mounting frees up floor space in tight rooms and improves airflow geometry.

The competition — air purifiers we considered but didn't pick

Several well-known air purifier brands came up in research and didn't make the final shortlist. For transparency:

• IQAir HealthPro 250 / 350: Premium Swiss-engineered medical-grade air purifiers used in hospital cleanrooms. Sold predominantly via specialty health and allergy retailers (IQAir Australia, Air Purifiers Direct), not Amazon AU. ~$1,500-$2,500 entry. Only worth considering if you have severe allergies or asthma and have already exhausted what consumer HEPA can do.
• Molekule Air Pro: American brand using "PECO" photoelectrochemical oxidation tech. Independent testing (Consumer Reports, Wirecutter) has been mixed — the technology breaks down VOCs effectively but particle capture is no better than standard HEPA at 3x the price. Sold via molekule.com.au and specialty retailers. Not recommended for general use.
• AirDoctor Pro 5000: American brand popular in allergy-community circles, "UltraHEPA" claim that's marketing-speak for H13 with denser pleating. Sold via airdoctor.com.au directly, intermittently on Amazon AU. Solid product, but at a ~$799 entry price its particle capture isn't meaningfully better than the True HEPA picks above at a fraction of the cost — and it carries none of the Sensitive Choice certification the Coway Airmega 250 and 150 do.
• Xiaomi Mi Air Purifier 4 Lite: Was on our shortlist in earlier versions of this guide. Removed for the May 2026 v2 rebuild because Xiaomi doesn't maintain a direct Amazon AU buy-box — current listings are third-party seller (WOOYOOTE) imports at low stock at the time of writing, not the Xiaomi-direct supply chain. The product is fine; the AU availability isn't reliable.
• Blueair Blue Pure 411 / 3210: Swedish brand, well-respected internationally. The actual machine is structurally absent from Amazon AU's buy-box — searches return only replacement filters, not the units themselves. Sold in Australia via Air Purifiers Direct and breathesafe.com.au. If you specifically want Blueair, shop those retailers; Amazon AU isn't the channel.

Frequently asked questions

Do air purifiers actually help with allergies?

Yes — multiple clinical studies confirm HEPA air purifiers significantly reduce airborne allergens including dust mite droppings, pollen, pet dander, and mould spores. A 2020 study in the Journal of Allergy and Clinical Immunology found running a HEPA purifier in the bedroom reduced nighttime allergy symptoms by 30-50%. The key: use a genuine H13 HEPA filter (not "HEPA-type") and size the purifier correctly for your room. Running a purifier 24/7 in the bedroom is the single most effective placement for allergy sufferers.

Should I run my air purifier 24/7?

Ideally, yes — especially in the bedroom. Air purifiers work continuously, and turning them off allows particle levels to rise within an hour. Modern purifiers use 10-60 watts (similar to an LED bulb), so 24/7 operation costs $10-$30 per year. Most purifiers have an auto mode that runs on low when air quality is good and ramps up when particles are detected. Use auto mode for the best balance of performance, noise and running cost.

How often do HEPA filters need replacing?

Most manufacturers recommend every 6-12 months, but actual timing depends on air quality and usage. Live near a busy road, have pets, or recently endured bushfire smoke? Filters need replacing sooner. Many modern purifiers include filter-life indicators that monitor airflow resistance (Philips, the Coway Airmega line) — these are more accurate than timer-based reminders. Don't wash HEPA filters — water permanently damages the fibre structure. When the indicator says replace, replace.

What's the difference between True HEPA and H13?

"True HEPA" is a US marketing term; "H13" is the European EN1822 classification. They both refer to filters that capture 99.97% of particles at 0.3 microns. H13 is slightly more stringent (must capture 99.95% across a broader particle size range), but in practical performance the two are equivalent. Both are good. "HEPA-type" or "HEPA-like" filters meet neither standard — avoid those.

Do air purifiers help with bushfire smoke?

Yes, significantly. PM2.5 smoke particles are exactly what HEPA filtration is designed for. During the 2019-2020 fires, Australian households running HEPA purifiers reported substantially better indoor air quality even with windows sealed. The constraint is coverage and airflow — during heavy smoke events, you need a unit sized well above your room so it can keep up with smoke infiltration through door seals and gaps. If bushfire smoke is a recurring concern, err toward higher-coverage picks (Coway Airmega 250 at 131m², Coway Airmega Mighty at 109m², Philips 1000i at 78m² and 300 m³/h CADR).

What's the AU-vs-EU naming on the Philips 1000i / AC1715?

Same machine, different market badge. "1000i Series" is Philips's Australian naming convention for the i-Series line; "AC1715/70" is the model number printed on the back of the unit; "AC1715" is the US/EU naming. International reviews use the AC1715 designation; the Amazon AU listing uses "Philips 1000i Series Air Purifier" with AC1715/70 in the spec sheet. If you see any of these names, you're looking at the same product.

Will an air purifier help with mould?

Partially. HEPA filtration captures airborne mould spores — useful for symptom relief if you have mould allergies. But it doesn't fix the underlying mould problem. If you have visible mould or persistent musty smell, address the moisture source (look at our dehumidifier guide) and have the mould professionally remediated. The purifier supports symptom management; it isn't a substitute for fixing the cause.

Bundle this with — setting up your home's air quality

An air purifier handles airborne particles — but indoor air quality has multiple dimensions. If you're working through your first-home health setup, these guides cover the rest of the air-quality rotation:

• Cleaning products checklist — the full first-year cleaning kit, in priority order.
• Best dehumidifier in Australia — humidity control (the other half of the indoor-air-quality problem).
• Best portable air conditioner in Australia — temperature management when split-system isn't an option.
• Best split-system air conditioner in Australia — permanent climate control for the main living areas.
• Pet-proofing a new home — relevant if you bought a purifier specifically for pet dander.
• Bedroom essentials — the rest of the bedroom setup where your purifier runs 8 hours a night.
