What to Look for When Buying a HEPA Filter Air Purifier

When it comes to purchasing a HEPA filter air purifier, there are certain features you should be aware of to ensure you get the best value for your money. We recommend using a HEPA filter that can remove at least 99.97% of particles that are 0.3 microns or larger in diameter. Look for the Energy Star logo to make sure the air purifier doesn't consume too much energy and that standard shipping is free to the lower 48 states. We also offer 3-, 2-day, or next-day shipping for a variety of products.

The more certifications the unit has, the more valuable your purchase will be. CARB, AHAM, Energy Star, and UL are popular certifications for air purifiers. Additionally, having a warranty of at least 1 or 2 years ensures that your money is well spent. The Department of Energy (DOE) specifies that the HEPA filters used by DOE contractors must be able to remove 99.7 percent of airborne particulates of 0.3 microns or more, but there are no federal or national regulations for the consumer industry.

Manufacturers of high-quality HEPA filters voluntarily test and certify that their filters meet DOE standards, labeling them as “absolute HEPA” or “true HEPA”. Those whose filters do not meet DOE specifications are often labeled “HEPA type”, “HEPA type” or “HEPA type”. While they can be good filters, they haven't been tested or certified to meet the DOE standards for HEPA filters. A HEPA filter labeled “True HEPA” or “Absolute HEPA” has been tested and meets high efficiency criteria.

When looking for an air purifier, it's important to find one with a good fan speed range. If you need to clean the air in a room quickly, you want a powerful airflow, but a gentle airflow for use at night in the bedroom. An oscillating action is useful for covering more of the space in the room. Yes, by using HEPA filters in both vacuums and air purifiers, the user can reduce the amount of airborne allergens and pollutants in the home.

However, if you're very sensitive to air pollution, you may need to use your air purifier all year round. Most air purifiers have sensors to determine the amount of pollution in the air around them, along with other measures such as indoor air temperature and humidity. The ACH refers to the number of times an air purifier can filter the entire volume of air in the treatment space every hour. While some filters are difficult to clean without damaging them, users may be able to put up with a few more months or more cleaning a HEPA filter.

One of the most popular products available in the constant search for cleaner air, especially for allergy sufferers, is the High Efficiency Particulate Air Filter (HEPA) found in several air cleaning products. Air purifiers that can clean the air in a space at least four times an hour are best for allergy sufferers and asthmatics. Using an air purifier will help create cleaner, healthier air in your home or office so you can enjoy better indoor air quality. In the 1960s, HEPA filters were already being used in hospitals to help stop the spread of germs and particulates in the air, and soon after they began to appear in appliances such as vacuums, air purifiers, and whole-house air filtration systems.

If pollen or related allergies prevent you from opening windows, run the air conditioner or forced air cooling system with a clean air filter. It's cheaper to be able to wash and reuse a filter than to have to buy a replacement one every time, especially if you're going to use the air purifier frequently. Smart air purifiers come with smart features such as air quality monitoring, Wi-Fi connectivity, and a programmable timer that set them apart from classic models. Carefully consider the type of filter and technology of an air purifier and compare it to your needs before you buy it.

A whole-house HEPA air purifier connects to the main trunk of a home's HVAC intake duct and filters out harmful contaminants every time the oven or air conditioner is running.
