An air purifier helps reduce airborne allergens like pollen, dust mites and pet dander. With high-efficiency HEPA filtration, it continuously captures these particles to keep your indoor air cleaner, fresher and more comfortable.

Spring rolls around, the windows stay shut, and you're still reaching for a tissue indoors. So does an air purifier actually help with allergies?

What an air purifier actually catches

A HEPA H14 filter captures up to 99.995% of particles down to 0.1 microns, including pollen, dust mite allergens and pet dander. As air passes through the filter, these particles are captured rather than continuing to circulate through the room.

That means your air purifier is continuously working to reduce airborne allergens in the air you breathe. The more air it filters, the more opportunities it has to capture these particles throughout the day.

Do home air purifiers actually make a difference?

Yes. An air purifier continuously filters the air in your room, capturing airborne allergens before they can continue circulating.

For people who want to create a cleaner, fresher indoor environment, this makes an air purifier a valuable addition to their everyday routine. Instead of simply letting airborne particles circulate, Purevo continuously works to capture them.

Is it okay to sleep in a room with an air purifier?

Many people choose a lower fan setting at night for quieter operation, while the purifier continues capturing airborne particles and helping maintain a fresher-feeling room.

Allergies and pets together

If pet dander is part of the picture alongside seasonal allergies, an air purifier can help capture both.

The HEPA filter captures particles based on their size, meaning it can capture airborne particles from different sources, including pollen, dust mite allergens and pet dander.
