Filter 7 facts
- HEPA filter class
When it matters
- Allergy to pollen, dust mites or pet dander.
- Fine dust from traffic, wood stoves or wildfire smoke.
When it matters less
- For smells alone the particle filter’s class decides little: the carbon filter does that work.
Source: Manual · checked on 3 Nov
How fine the filter is. True HEPA and H13 catch at least 99.97% of particles at 0.3 microns. HEPA-type is a weaker claim with no test behind it.
- True HEPA
- Filter layout
When it matters
- Cooking or smoke, which wears out the carbon layer before the particle layer.
- Keeping the cost of filters down over the years.
When it matters less
- With no carbon filter in the purifier it decides nothing.
Source: Manual · checked on 3 Nov
Whether the particle and carbon layers are one filter or separate ones. Separate filters let you replace only the part that is spent.
- Separate filters
- Activated carbon filter
256 of the 264 models we track have this.
When it matters
- Cooking smells, smoke and pet odours.
- Gases from new furniture, paint or cleaning products.

How the purifier tells you the filter is due. A timer counts the hours it has run, a sensor judges the filter itself, an estimate weighs the hours against the air it cleaned, and a plain indicator is one the maker does not explain.

The maker
Fellowes
- Headquarters: United States
- Founded in 1917
Fellowes traces its start to 1917, when Harry Fellowes took over a record storage box and registered the company as The Bankers Box Company. Its corporate headquarters are in Itasca, Illinois, in the United States. The company is still owned and led by the Fellowes family, now in its fourth generation. It widened its brand from paper shredders to areas such as air purification. Its Dutch site says an air purifier with HEPA filtration can remove nearly all (99.95%) airborne particles of 0.3 micron.
