An air purifier with HEPA filtration can effectively capture airborne mould spores. Purevo's HEPA H14 filter captures up to 99.995% of particles down to 0.1 microns, helping keep your indoor air cleaner.

Mould spores can become airborne and circulate through your home. So can a purifier actually capture them?

Will an air purifier catch mould spores?

Yes. Mould spores typically range from 2 to 10 microns, while a HEPA H14 filter is rated to capture up to 99.995% of particles down to 0.1 microns.

As air passes through the filter, airborne mould spores are captured alongside other fine particles, helping reduce what is circulating through your indoor air.

What takes mould spores out of the air?

HEPA filtration is designed to capture fine airborne particles. As your purifier draws room air through its filter, particles are trapped within the filtration system.

Purevo's HEPA H14 filtration provides high-efficiency particle capture, helping continuously filter mould spores, dust, pollen and other airborne particles.

Did you know?

HEPA is a tested filtration standard designed to capture fine airborne particles.

Activated carbon helps absorb unwanted odour molecules from the air.

HEPA H14 filter captures up to 99.995% of particles as small as 0.1 microns.

What an air purifier does not do

An air purifier is designed to filter airborne particles, making it a valuable part of maintaining cleaner indoor air.

If mould is already growing on a surface, that area should still be cleaned and the underlying moisture source addressed. The purifier can then help by continuously filtering airborne particles in the room.

How do I know if my air purifier will pick up mould spores?

Check the filter grade. HEPA H14 filtration is rated to capture particles down to 0.1 microns, well below the typical 2–10 micron size of mould spores.

Room size and CADR are also important because they determine how much air your purifier can process.

Is there a way to check for mould spores in the air?

If you're concerned about airborne mould spores, professional indoor air quality testing can provide a more detailed assessment.

In everyday use, choosing a purifier with high-efficiency HEPA filtration and the right room coverage gives you an effective way to continuously filter airborne particles.

Purevo Air PRO uses a HEPA H14 filter capturing up to 99.995% of particles down to 0.1 microns, well within the range that covers mould spores, across up to 70m². The filter slides in without tools and is replaced roughly every 6 months.
