High-efficiency particulate air (HEPA) filters can remove 99% of airborne particles, including common allergens such as dust and pet dander. Many companies make air purifiers that use HEPA filters.
The whole home air purifier is a pre-filter, silver filter, pure HEPA filter and allergens, dust, pollen and other air pollutants on the order of 0.3 microns. An interior that releases negative ions into the environment is used to bind to and kill allergens on contact.
I love the cool display panel on my whole home air purifier, which uses sensors to indicate filter life and detect allergens in the air. Various fan speeds can also be set in the automatic mode setting. Praise WhisperMax technology. This allows it to operate very quietly without compromising efficiency. In addition to the 9 to 12 month filter life, which runs 24/7, maintenance is negligible. Compare with the best personal air purifiers that have up to filter life and maintenance information button.
Find the right air purifier
How to choose the right air purifier for your home with all models and features available? The most important detail is the size of the room where the air filter is primarily used. Are you looking for AHAM Verifide? Label. CADR (Clean Air Delivery Rate) is shown for the air filter and recommended room size.
CADR is a measure of an air purifier's filtering rate of three common size particles (dust, pollen and tobacco). The higher the number on the label, the faster the air filter will purify the air. But don't just choose the air purifier with the largest number. They can be too large for the room, causing unnecessary use of energy and noise. If the form is too small, the task may not be completed. Follow the 2/3 rule and choose an air purifier with a degree of cigarette smoke that is two-thirds the size of a room. This means that a 200-square-foot room will require an air purifier with a CADR of at least 132 cigarettes of cigarette smoke.
CADR also provides a way to choose an air purifier based on your air purification needs. If you live in an area with a high pollen count, consider using a highly rated air purifier to filter pollen. If dust is a problem, pay attention to the unit's dust rating.
An air purifier's noise level depends on its operating setting, but most air purifiers can generate noise in the 35 to 70 dB range. To avoid sleep disturbances, choose an air purifier at that is effective when set to low operating settings and therefore has a low noise level.For bedrooms, you can also check if the unit has a night atmosphere.
