We Compared The 5 Most Popular Air Purifiers
After comparing five of the most popular models, the same issues kept showing up — here's what to watch for.
5 popular air purifiers put to the test
To find the best option for Australian homes, we compared leading air purifiers on real ownership — not just brochure specs. Every unit was evaluated on the same five criteria:
Filtration performance
Ongoing filter / running cost
Washable & reusable system
Independent lab testing
Long-term support & parts
OUR TOP PICK ↓
WINNER 2026 AIR TEST
#1 AirRepair Plus
Our top pick for Australian homes
AirRepair is the purifier you wish you had bought sooner. On paper the specs look strong — and in real homes it delivers.
Instead of locking you into disposable HEPA cartridges every 6–12 months, AirRepair uses washable reusable electrostatic collector plates. Clean the plates, put them back, and keep purifying — with $0 spent on replacement filters year after year.
It removes everyday particles like dust, pollen and pet dander, and is backed by independent testing plus local Aussie support. For households that want cleaner air without the waste and ongoing filter bill, it was the clear winner.

#2: Philips PureProtect 2200
Independently verified testing - most brands don't bother running. The 109 sqm coverage claim sits at roughly 1.6 ACH — better than most in this comparison, but real coverage at the recommended 4 ACH is closer to 44 sqm. The filter is disposable, not washable: longer lasting then most, but a whopping $109 a pop.

#3: Levoit Core 300
The Core 300 is affordable, quiet, and cleans the air well compared to the smaller Levoit models. The catch is the disposable filter: $49 every 6–8 months, or roughly $100 a year, for as long as you own it. Coverage also tops out around 20 sqm, so it's built for a bedroom, not a living space.

#4: Shark NeverChange Air Purifier MAX
Shark's top of the range model looks strong: "130" sqm coverage and a "5-year" filter. Neither holds up. The 130 sqm "figure" is based on just 1 ACH — at the recommended 4 ACH, real coverage is closer to 32 sqm. The filter tells a similar story: independent testers estimate 1–2 years, not 5, plus a separate odor cartridge every 3–6 months.

#5: Dyson Purifier Cool TP07
The Dyson looks the part — sleek design, app control, a $949 price tag to match. As a fan, it's genuinely good. As a purifier, it's a different story. Dyson doesn't publish a CADR for this model — Independent testing found it cleans air about as effectively as leaving the window open and hoping for the best. Great for a hot day. Not much else.
