Best picks
Winix identifies Filter O for the Zero Compact as H13 HEPA. The other four models have useful particle-filtration claims, but their supplied manufacturer pages do not establish H13 or an equivalent filter class.
Quick answer
A “HEPA” label is useful only when the filter class and evidence are clear. WINIX identifies the Filter O used by Zero Compact as H13 HEPA and publishes a 99.97% figure at 0.3 microns. That makes it the only H13-confirmed model in this five-product evidence set. Philips, Levoit and Blueair publish particle-filtration information, but the pages available here do not establish H13 or an equivalent class, so they remain candidates rather than verified H13 recommendations.

Verified H13 HEPA filtration in this evidence set
WINIX identifies Filter O for Zero Compact as H13 HEPA and states 99.97% filtration at 0.3 microns. The product page gives a 250 m³/h CADR and maximum 50 m² room figure. The manufacturer, not Gearjury, supplies these performance claims.
Official manufacturer image
Verification candidate — compact model
The permitted Philips source gives room, CADR and noise specifications but does not document a True HEPA H13 or equivalent filter grade. Do not treat this as a verified HEPA recommendation.
Official manufacturer image
Verification candidate — smart controls
The supplied UK page documents sleep mode and room-size assumptions but not a True HEPA H13 or equivalent filter grade. Confirm classification with the manufacturer before considering it for this list.
Official manufacturer image
Verification candidate — published CADR
The UK page lists a 243 m³/h CADR and room coverage but does not document a True HEPA H13 or equivalent grade in the permitted source pack.
Official manufacturer image
Verification candidate — smaller rooms
The manufacturer page gives room-size, noise and CADR information, but the allowed evidence does not establish a True HEPA H13 or equivalent filter grade.
| Model | Manufacturer filter evidence | H13 or equivalent class confirmed here? | Published room/CADR information |
|---|---|---|---|
| Winix Zero Compact | Filter O is identified as H13 HEPA; 99.97% at 0.3 microns | Yes | 50 m² maximum; CADR 250 m³/h |
| Philips AC0820/10 | NanoProtect HEPA and particle-performance claims | No H13 class established by the supplied page | 20 m² cleaning-time basis; CADR 190 m³/h |
| Levoit Core 300S | Personal HEPA replacement-filter claim | No H13 class established by the supplied page | 50 m² at 2 ACH; CADR not supplied |
| Levoit Vital 100S | Main-filter particle-performance claim | No H13 class established by the supplied page | 20.8 m² at 5 ACH; CADR 243 m³/h |
| Blueair Blue Pure 511 | HEPASilent particle-filtration claim | No H13 class established by the supplied page | About 16 m² at 4.8 ACH; CADR supplied in cfm |
“HEPA-type” or a branded filtration name should not be presented as H13 without a manufacturer class or equivalent test basis.
Common questions
That depends on the filter class, room size, airflow and running costs. WINIX supplies H13 evidence for Zero Compact in this set; verify the exact filter and room basis before buying.
It depends on what you want to address and whether a model is suited to your room. Compare independently supported specifications and check the filter grade before buying.
The supplied sources contain product specifications, not clinical evidence. We do not make claims about asthma outcomes.
A documented filter class, suitable CADR and correct room sizing matter. WINIX identifies the Zero Compact filter as H13 HEPA; the other candidates here still need class confirmation. Manufacturer figures do not predict the result in every home.
This page covers room air purifiers and does not assess vehicle-specific products.
The supplied product sources do not test odour removal for dog smells. Check for manufacturer evidence about activated carbon and odour performance.
No pet-dander outcome data is included in the allowed source pack. Check the filter specification and room-size guidance, and avoid treating this shortlist as a verified HEPA recommendation.
Price alone does not establish performance. Compare a product’s documented filter grade, CADR and room-size assumptions; prices are not included in this source pack.
We checked the supplied manufacturer evidence and UK catalogue for models with active UK offers and official product images. The allowed evidence pack does not identify a True HEPA grade (H13 or equivalent) for any candidate. The five records below are verification candidates only, not confirmed HEPA picks. Gearjury has not physically tested these products.

The Levoit Vital 100S and WINIX ZERO Compact publish CADR figures in m³/h. We compare five models by manufacturer data, with room-size assumptions and missing costs made clear.
Philips AC0820/10 leads with a 19 dB(A) sleep mode in manufacturer data. Levoit, Blueair and Winix cover other bedroom needs, from small rooms to larger spaces.
