How Do They Work?

HEPA is an acronym that stands for High-Efficiency Particulate Air, so a HEPA filter is a High-Efficiency Particulate Air filter. A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. Filters, whether for an air cleaner or other implementation, come with many benefits and claims.

Pro Tip Hepa

They use filters to filter allergens and pollutants from the air. Air filters utilize fine sieves to filter particles like dust, smoke, allergens and other pollutants. The finer the sieve you use, the smaller the particles it traps.

The HEPA Guarantee

The High-Efficiency Particulate Air (HEPA) filters which are guaranteed to catch 99.97% of airborne particles larger than 0.3microns set the benchmark for air filters. HEPA filters remove smaller allergens like dust, chemicals, asbestos, smoke, pollen and pet dander. The more times air passes through the HEPA filter, the cleaner the air become.

Q: What Is a HEPA Filter?

A: A HEPA filter is a device that traps and blocks small particles from going back into the air. A certified HEPA filter is essential and is tested to trap particles as minute as .3 microns with 99.97 % efficiency. One micron is 1/1,000,000 of a meter. A 0.3-micron particle is 300 times smaller than a human hair and 30 to 50 times smaller than the human eye can see. They help make your environment fresh and crisp. HEPA air purifiers are proven to be the most effective air units in the war against pollutants and toxic air impurities.

Q: Which Ones Are the Best For Allergy- And Asthma-Sufferers?

A: Proper air purification is vital for homes of allergy- and asthma-sufferers since allergens and asthma triggers can conveniently find their way into your homes, despite your best attempts. HEPA Air Purifiers are the best and premium choice for these sufferers since they help eliminate up to 99.97% of allergens up to 0.3 microns in size from your environment. The IQAir HealthPro Plus and the Honeywell 50250-s True HEPA Round Air Purifier are both excellent and premium choices for sufferers of allergy and asthma. These units feature the incredible multi-stage air filtration, which consists of a particle pre-filter, a HEPA filter, and a carbon filter. So, you can always rely on these HEPA sensations to make your health better.

Q: What Is CFM?

A: CFM represents Cubic Feet per Minute. The CFM measurement represents the cubic feet of air that moves through the unit per minute. It is incredibly vital when considering the air purifier system that is perfect for you and the higher the CFM, the better potential air purification results.

You need always to remember that a variety of factors impact the CFM. These include fan speeds, insulation, air flow in the room, the furniture in the room, and amount of impurities in the air. Unfortunately, there is an equation that will help you determine an ideal CFM, which can provide help when deciding on air purifiers.

To find the ideal CFM, you need to calculate the total volume of your space (length x width x height in cubic feet) and divide this number by your desired ACH (Air Changes per Hour).
