Air purifiers sanitize the air of allergens, pollutants, and toxins to improve indoor air quality. They work by sucking in air, “cleaning” it, and recirculating it. Air purifiers remove harmful particles from the air you breathe by trapping them in an activated carbon filter or purifying them with a HEPA filter before releasing them. Filters must be changed periodically to keep your air purifier working optimally. How often you must change your unit’s filter depends on the brand you buy. The most effective air purification systems do not use washable and reusable filters.

The best HEPA air purifier is safe for use because they do not emit pollution. They collect airborne pollutants and trap them within their fibers. Make sure you choose a unit that has a true HEPA filter and not a HEPA-type filter. HEPA-type filters are OK for removing larger particles like pet hair, but they are ineffective at tackling smaller size particles like those in smoke, dust, and pollen.

A HEPA air purifier uses HEPA filtration to clean indoor air. HEPA filters remove 99.97 percent or more of airborne particles sized 0.33 microns or larger. HEPA filters are made from either these two materials: fiberglass or nonwoven fabric like polypropylene. Oransi uses both kinds of HEPA filter materials.

Many air purifiers on the market give a blanket specification for room coverage, which does not help consumers know what to expect. Before you select the best air purifier for your commercial or residential space, you must first determine square footage. For example, if you want a purifier for your living room, a desktop model is not suitable. As a rule, larger rooms require more filtration.

Oransi air purifiers are top-rated for one simple reason: they work! Clemson University rated Oransi as its number-one choice for microbe-free air. Independent testing conducted by Clemson revealed Oransi was the top performer out of four brands for removing bacteria, dust, mold, and pollen. For individuals with indoor allergies, Oransi’s products are second to none.

Clemson University is not alone in its endorsement of Oransi as the best air purifier consumers can buy. Other accolades include:

• Modern Castle rated Oransi’s EJ120 as the best carbon and HEPA air purifier. With a MERV rating of 17, it is one of the best HEPA air filters.
• Women’s Health magazine named Oransi its 2019 Editor’s Choice in the “Fresh Air Faves” category.
• Huffington Post called the EJ120 the “Tesla of air purifiers” for its high-quality design and performance.
• CNN touted the EJ120 as the best HEPA air purifier for large homes for its ability to effectively clean indoor spaces up to 1,500 square feet.

CADR is the gold standard for measuring air purifier performance in the U.S. since 2016. CADR ratings give consumers a reliable way to compare air purifiers using quantifiable data. Top-rated air purifiers do not need fancy marketing messages to attract buyers when they have CADR ratings to back up their claims about their products.

The Association of Home Appliance (AHAM) sets the industry standard for air purifier testing. Oransi’s EJ120 air purifier is the only American-made air purifier that earned an Energy Star Rating with a high CADR Rating from AHAM. CADR stands for Clean Air Delivery Rate. It is a metric developed for measuring the performance of residential air purifiers.

Why is CADR rating so important? CADR rating measures how many cubic feet of air per minute an air purifier can clean. CADR assesses the effectiveness of filtering indoor air of dust, pollen, and smoke. The best air purifier scores a high rating of 450 for smoke and pollen and 400 for dust.

Air purifiers with large surface area filters and strong fans have the highest CADR ratings. However, CADR has its limitations. Ratings are focused on particle removal rather than gas removal. CADR also considers noise levels for the highest fan speeds.
