Air Purifiers and Humidifiers FAQs

Do humidifiers help with air quality?

Humidifiers are responsible for adding moisture to the air, helping to relieve congestion and dryness that could cause skin irritation and other issues. Purifiers with filtration systems are more synonymous with air quality, in that they remove airborne pollutants from the air. We prefer having a humidifier and air purifier together.

Is it OK to leave the air purifier on all night?

Yes, the best practice is to leave an air purifier on all night, as it'll result in maximum efficiency. An always-on air purifier can refresh a room several times an hour depending on its CADR and square footage ratings. With airborne pollutants a never-ending affair, you can leave the air purifier on all night without breaking the bank on energy bills.

Does air purifier make air dry?

No, air purifiers do not leave air dry, as they are not capable of removing moisture from the air. Moisture also does not penetrate air purifiers, so both are mutually exclusive.

Can dirty humidifiers make you sick?

Yes, a contaminated mist or stream can definitely cause breathing and lung-related issues. Asthma and allergy sufferers are particularly vulnerable.
