Both air purifiers started making loud high pitched aggressive noise after 3 years of daily use. The noise level was louder and more obnoxious than the noise Winix already makes when running normally.

Buying Guide for HEPA Filter Air Purifiers

HEPA filters and air purifiers are the gold standards in air purification. These air purifiers reduce air pollution, allergens, and other airborne contaminants by trapping pollutants, allergens, and other airborne contaminants in their high-efficiency filters. They work by removing airborne particles from the air using a HEPA (High-Efficiency Particulate Air) filter. This makes them ideal for people who suffer from allergies or asthma, as they can help to reduce the number of allergens in the air. The HEPA filter in air purifiers is also useful for removing smoke, dust, and pet dander.

Air purifiers with HEPA filters may be more expensive, but they offer superior performance and are a good option for allergy and respiratory sufferers. You can check out Amazon for some of the exclusive selections of the best HEPA filter air purifiers available at great prices.

Benefits of HEPA Filter Air Purifiers

Removal of Dust

HEPA air purifiers are intended to remove dust from the air. They function by trapping dust particles with a HEPA filter. Small and lightweight dust particles are easily blown by wind. HEPA filters are very efficient at trapping these particles.

Pollen & Allergens

HEPA (or High-Efficiency Particulate Air) filters are the most advanced and can capture allergens as small as 0.3 microns. They accomplish this by trapping the particles in a woven mesh filter. They prevent the particles from being released back into the air and so they are an excellent product for people who suffer from seasonal or all-year allergies.

Removal of Odors

HEPA filter air purifiers are an efficient way to remove odors from the air. HEPA filters are capable of removing particulate matter from the air by utilizing the power of negative air pressure. The HEPA filter collects particulate matter, which is then safely deposited into a bin that can be removed and emptied when full. This filter prevents particulate matter from being recirculated.

Reduction of Mold & Mildew

Mold and mildew are effectively reduced indoors by HEPA filter air purifiers. This is due to their ability to remove mold and mildew spores from the air via the filtration process. This assists in removing the source of mold and mildew and reducing their spread inside your home.

Factors to Consider before Buying HEPA Filter Air Purifiers

Size

HEPA filters come in a variety of sizes, including small, medium, and large. The size of the HEPA filter is important because it determines how much dust and other particulate matter can be captured by the filter. A small HEPA filter is appropriate for a small room, whereas a large HEPA filter is appropriate for a large room. It is critical to select the HEPA filter size that is appropriate for the size of the room. For example, a large filter is appropriate for a room of 2000 sqft.

Noise Level

Before purchasing a HEPA Filter Air Purifier, make sure to check the noise level because it will directly affect your comfort while using it. A higher noise level indicates that the purifier will be more obtrusive and may interfere with your sleep or concentration. We recommend buying a HEPA filter air purifier than operates within 40dB.

Number of Filtration Stages

Consider the number of filtration stages when buying HEPA filter air purifiers. Having multiple filters allows the purifier to capture more airborne contaminants, which means cleaner air for you and your family. Multi-stage air purifiers typically have a longer lifespan than single-stage purifiers. We recommend going for a filter with more than 3 stages.

Built-In Timer

A lot of air purifiers on the market don't have a timer, which means that they will run until they are turned off. This can be a problem if you forget to turn it off, as it will continue to run and use up energy. The built-in timer ensures that the air purifier turns off automatically after a predetermined amount of time.

Conclusion

You should consider a HEPA filter air purifier if you're looking for an air purifier that can effectively remove contaminants. HEPA filters can remove 99.97% of airborne particles with diameters of 0.3 microns or larger, making them extremely effective at trapping pollutants like dust, pollen, and pet dander. HEPA filter air purifiers do not produce any harmful ozone gases, making them a safer choice than other types of air purifiers.

There are a variety of home air purifier parts and accessories available to help you get the most out of your air purifier. By perusing the best products we've featured, you can gain a better understanding of your purchasing options. We review and recommend top rated value HEPA filter air purifiers based on design, performance, money value, and ease of use.
