Best overall: Philips 1000i Series (AC1715)
The AC1715 is the air purifier we’d recommend to most Australians. It covers rooms up to 78 m² — living rooms, open-plan areas, master bedrooms — with a 300 m³/h clean air delivery rate, meaning it can cycle the air in a medium room in well under 10 minutes. The two-stage filtration (HEPA plus active carbon) handles both particles and odours, which is more than particle-only budget units manage.
The AeraSense sensor gives you a live readout of your air quality, and the Air+ app lets you monitor and control it remotely. It works with Alexa and Google Assistant if you want voice control.
Price-wise, this is where it gets interesting. RRP is $349 (David Jones), but we’ve seen it for $285 at Dick Smith and $278.75 via buywisely’s price comparison — and Myer currently has it on clearance at $225, down from $349. At clearance pricing it’s genuinely the best value HEPA purifier in Australia right now. Clearance stock is finite, so the $285 Dick Smith price is the more reliable “street price” to budget around.
Who it’s for: most households. Allergy sufferers, pet owners, anyone in a bushfire-smoke-prone area.
Key specs: 78 m² coverage · 300 m³/h CADR · HEPA + active carbon · AeraSense sensor · Air+ app · Alexa/Google support
Price: $285 at Dick Smith, $225 at Myer (clearance, was $349), $349 RRP (checked 13 October 2026)
Verdict: the best all-round air purifier you can buy in Australia. Genuine HEPA filtration, big-room coverage and smart features at a mid-range price — especially sharp on clearance.
Why you’ll love it
- Genuine HEPA + carbon filtration for a $225–$285 street price
- 78 m² coverage suits open-plan living
- 15 dB sleep mode is genuinely whisper-quiet
- Air+ app with live AeraSense air-quality readout
Reasons to be cautious
- Myer $225 clearance stock is finite
- Turbo mode hits 50 dB
- No fan function, unlike the Dyson TP07

Best budget: Xiaomi Smart Air Purifier 4 Lite
If your budget tops out under $250, the Xiaomi 4 Lite is the one to beat. It delivers a 360 m³/h CADR — actually higher than the Philips on paper — with triple-layer filtration that Xiaomi rates at 99.97% of 0.3-micron particles. It covers 25–43 m², which suits bedrooms and home offices, and the Mi Home app gives you remote control and air quality monitoring.
The honest caveats: it’s a smaller-room unit, the filtration isn’t certified HEPA-13 (Xiaomi markets it as “True HEPA”), and stock is a genuine problem — it’s currently out of stock at Panmi Shop, Xiaomi’s authorised Australian reseller, which lists it at $239. HomeCell lists it at $145, though they’re a lesser-known retailer, so weigh that saving against after-sales support.
Who it’s for: bedrooms, studies and renters who want effective purification without spending $300+.
Key specs: 25–43 m² coverage · 360 m³/h CADR · triple-layer filtration · Mi Home app · 4.8 kg
Price: $239 at Panmi Shop (currently out of stock), $145 at HomeCell (checked 13 October 2026)
Verdict: the best budget pick when you can actually buy one. Set a stock alert at Panmi rather than paying grey-import prices elsewhere.
Why you’ll love it
- 360 m³/h CADR beats pricier rivals on paper
- 33.4 dB night mode suits bedrooms
- Compact 4.8 kg footprint
- Mi Home app plus voice control
Reasons to be cautious
- Frequently out of stock at Australian resellers
- Filtration not certified HEPA-13
- 25–43 m² limit — not for open-plan
- Only a 1-year warranty via resellers

Marked down on brand presence and warranty: Xiaomi's AU purifier support runs through resellers, and stock is unreliable.
Best premium: Dyson Purifier Cool TP07
The TP07 is two appliances in one: a bladeless tower fan and a sealed HEPA H13 purifier. Dyson’s whole-machine sealing means what goes inside stays inside — the air that comes out is genuinely clean, rated at 99.95% of ultrafine particles down to 0.1 microns. It’s tested for an 81 m³ room, has 10 fan speeds, night mode, and connects to the MyDyson app with detailed pollutant reporting.
You’re paying for the Dyson engineering and the fan function. At $949 RRP (confirmed at dyson.com.au, Domayne and in CHOICE’s review) it’s firmly premium. Kogan has listed it on sale at $649 in the Black/Nickel colourway — worth checking before you pay full price, as Dyson purifiers do cycle through discounts. Note the White/Silver variant is currently out of stock on dyson.com.au.
One honest note from owner reviews: as a fan, the airflow is gentler than a cheap pedestal fan. Buy it as a purifier that also cools, not as a fan that also purifies.
Who it’s for: buyers who want one premium unit for a living room or bedroom, and value the fan function for summer.
Key specs: HEPA H13 sealed system · 99.95% @ 0.1 micron · 81 m³ room coverage · 10 speeds · MyDyson app · remote
Price: $949 RRP (dyson.com.au, Domayne); Kogan has listed $649 on sale — check before buying (checked 13 October 2026)
Verdict: the premium pick. Superb purification with a genuinely useful fan built in — but only worth it if you’ll use both functions.
Why you’ll love it
- Sealed HEPA H13 — what goes in stays in
- Doubles as a bladeless tower fan
- Detailed pollutant data in the MyDyson app
- Filter claimed to last up to 5 years
Reasons to be cautious
- $949 RRP is steep if you won't use the fan
- 61.5 dBA at max is loud
- Dyson publishes no CADR figure
- White/Silver colourway often out of stock

Top marks for engineering and support; value is the drag at $949 RRP. The $649 Kogan sale price would lift this score.
Best for large rooms: Dyson Purifier Big+Quiet Formaldehyde
For open-plan living areas up to 100 m², nothing else on this list comes close. The Big+Quiet uses Dyson’s conical airflow design to project purified air up to 10 metres, and it’s engineered to stay quiet while doing it — a real consideration when a purifier needs to run all day in your main living space. The formaldehyde-destroying catalytic filter is a genuine differentiator if your home has new furniture, flooring or cabinetry off-gassing VOCs.
At $1,499 RRP it’s the most expensive unit here by a long way. The Good Guys has listed it at $999 as an in-store-only offer, which is worth chasing if you have one nearby. Don’t count on the EOFY $899 deal returning — that was a June promotion and it’s gone.
Who it’s for: large open-plan homes, new builds with off-gassing materials, anyone who needs serious coverage without serious noise.
Key specs: up to 100 m² coverage · HEPA 13 + K-carbon + formaldehyde catalytic filter · quiet conical airflow · MyDyson app
Price: $1,499 RRP (dyson.com.au, Myer); $999 at The Good Guys (in-store only) (checked 13 October 2026)
Verdict: overkill for a bedroom, essential for a big open-plan space. Buy it for the coverage, not the badge.
Why you’ll love it
- Purifies up to 100 m² — nothing else here comes close
- Formaldehyde-destroying catalytic filter
- Engineered for low noise at high airflow
- HEPA up to 5 years, K-carbon up to 2 years
Reasons to be cautious
- $1,499 RRP — the most expensive here by far
- 11.9 kg — not moving room to room
- Overkill for bedrooms
- Replacement filter pricing is opaque
Score 8.0/10 — essential for big open-plan spaces, overkill elsewhere.

A perfect features score can't offset the $1,499 price — value carries 30% of the weight in our rubric.
Cheapest option: Kogan Ion & UV Air Purifier — with caveats
At $109 from Dick Smith, the Kogan Ion & UV is the cheapest air purifier we’d mention at all — and it comes with significant caveats. It uses ioniser and UV technology rather than a HEPA filter, and Kogan doesn’t state a HEPA rating or a CADR figure. That means we can’t verify how effectively it actually cleans air.
CHOICE generally advises caution with ioniser and UV-only models, and we’d echo that: this is not in the same league as the HEPA units above. If your budget is genuinely capped at ~$100 and you mainly want odour reduction in a small room, it’s an option. But stretching to the Xiaomi at $145–$239 buys you a fundamentally better class of filtration.
Who it’s for: only as a last resort on a strict sub-$120 budget.
Key specs: ioniser + UV (no HEPA rating stated, no CADR stated)
Price: $109 at Dick Smith (presale listing, checked 13 October 2026)
Verdict: the cheapest, not the best value. We’d rather you bought the Xiaomi — but we’d rather you knew this exists than bought a no-name import with no local support.
Why you’ll love it
- Only $109 — the cheapest mentioned here
- No filter to replace
- An option for odour reduction in small rooms
Reasons to be cautious
- No HEPA rating and no published CADR
- Ioniser/UV approach — CHOICE advises caution
- No published wattage or noise figures
- Fundamentally outclassed by the Xiaomi

Cheap means little when the core job — verified particle removal — can't be measured. No published CADR, no score for filtration.

*Dyson publishes airflow rather than CADR for the Big+Quiet. “Not published” means the manufacturer doesn’t state the figure — we don’t guess.
What each one costs to run per year
| Model | Est. electricity / yr | Filter | Est. filter / yr |
|---|---|---|---|
| Philips AC1715 | ~$25 | FY1700/30, 12 months | ~$55–$70 |

| Kogan Ion & UV | n/a (wattage not published) | None | $0 |
Electricity at max power, 8 hours/day, 32c/kWh (the default in our running-cost calculator). Auto mode draws far less, so real bills will be lower. †Xiaomi filter around $80 at AU resellers — re-check before buying.
We considered these — and ruled them out
- Levoit Core 300S — a US favourite, but with no official Australian distributor; warranty claims run through marketplace sellers
- Philips 800 Series — superseded by the 1000i at similar street prices; buy the newer model
- Dyson Purifier Hot+Cool HP07 — the same HEPA purification as the TP07 for around $350 more; most Australian homes don't need the heater
Ruling a product out isn’t a verdict against it — it just didn’t earn a top-pick slot this round.
How to choose an air purifier in Australia
Match the CADR to your room
CADR (clean air delivery rate) is the single most important spec. As a rule of thumb, you want a CADR in m³/h of roughly 4–5 times your room’s volume in m³ for effective cleaning. A 20 m² bedroom with 2.4 m ceilings is ~48 m³, so look for 200+ m³/h CADR. Buying an undersized purifier for a big room is the most common mistake — it’ll run constantly and never quite get there.
HEPA is the standard that matters
True HEPA (H13) filtration is the benchmark for capturing allergens, dust, pollen and smoke particles. Be wary of units that claim “HEPA-like” or “HEPA-type” without certification, and of ioniser/UV-only models that publish no CADR figure at all. If a manufacturer won’t tell you the CADR, that’s your answer.
Factor in filter replacement costs
The purchase price isn’t the total cost. HEPA filters typically need replacing every 6–12 months depending on use and air quality, and replacements for major brands run $50–$150+ in Australia. Dyson filters last longer (Dyson claims up to 5 years for the TP07 under normal use), which offsets some of that steep upfront price. Check replacement filter availability and price before you buy — a cheap unit with $120 filters is no bargain.
Noise matters more than you think
You’ll run this in your bedroom or living room for hours. Check the decibel rating on sleep/low mode — under 35 dB is genuinely quiet, over 50 dB will annoy you. The Xiaomi 4 Lite drops to 33.4 dB in night mode; the Dyson Big+Quiet is engineered specifically for low noise at high airflow.
Bushfire smoke is a special case
During smoke events, a purifier with a high CADR and sealed HEPA system is genuinely effective — this is one of the few scenarios where air purifiers earn their keep in Australia. Size up: smoke penetrates everywhere, so buy for a larger room than you think you need, keep windows closed, and run it on high before dropping to auto.
Frequently asked questions
What is the best air purifier in Australia in 2026?
The Philips 1000i Series (AC1715) is our top pick — genuine HEPA + carbon filtration, 78 m² coverage and smart features for around $285 at Dick Smith, or $225 on Myer clearance while stock lasts (checked 13 October 2026). For a premium fan-purifier combo, the Dyson Purifier Cool TP07 at $949 RRP is the standout.
Do air purifiers actually work?
Yes — with the right expectations. A properly sized HEPA purifier measurably reduces airborne particles: dust, pollen, pet dander and bushfire smoke. What they can’t do is overcome open windows, stop surface dust from settling, or fix poor ventilation. Think of one as a strong supporting player, not a magic box — and always match the CADR to your room size.
How much should I spend on an air purifier in Australia?
The sweet spot is $225–$350. At $225–$285 the Philips AC1715 gives you genuine HEPA filtration for a large room; $239 gets the Xiaomi 4 Lite for bedrooms. Below $150, filtration quality drops off sharply — the $109 Kogan is the floor, and we’d steer most buyers toward the Xiaomi instead. Premium starts at $949 (Dyson TP07) and $1,499 (Dyson Big+Quiet) for large spaces.
How often do air purifier filters need replacing?
Typically every 6–12 months for standard HEPA units, depending on usage and how polluted your air is. Dyson claims up to 5 years for the TP07’s filter under normal conditions. Budget $50–$150+ per replacement for major brands in Australia, and check that replacements are actually stocked locally before you buy the unit.
Are ioniser or UV air purifiers as good as HEPA ones?
No. HEPA filtration is the proven standard for removing particles from air, with published CADR figures you can compare. Ioniser and UV-only models (like the $109 Kogan) generally publish no CADR, and CHOICE advises caution with them. Some ionisers can also produce ozone as a byproduct. If clean air is the goal, buy HEPA.
