After searching the air purifier, you quickly find out that you can't just pick a random air purifier and buy it. You will find that there are thousands of air purifiers out there, including hundreds of types of air filters.

Don't worry, this guide will teach you everything you need to know about Air Filter Forms.

Yeah, we 're going to give you everything!

Since there are only 4 specific forms of air filter technology widely used by these air purifiers, you can easily test each of them out.

Types of air filters:

  • HEPA Air Filter
  • Ionic Air Filter
  • Activated Carbon Filter
  • UV Light Air Filter

    Air filter forms are the first thing people are searching for before they make any decision to buy an air purifier. Remember that we are providing instructions to the air filters used in the air purifiers, which are kind of like this.

    Such four air purifying filters are used for various forms of indoor air pollution. We 're going to explain exactly how every one works.

    HEPA Air Filter

    The HEPA filter is the first and most well-known filter on the air purifier market today, making this air filtering method the highest quality for air purification. No matter how many times you've been searching for an air purifier or a vacuum cleaner, you'll come across the four-letter word "HEPA."

    The HEPA Air Filter is composed of: A very thick paper filter that catches airborne toxic pollutants (like dust , mold, pollen and even animal hair, and basically all that makes the air NOT CLEAN). This filter is degradable and must be replaced from 6 months to 1 year. High-end air purifiers usually have light notification for this routine replacement.

    The HEPA pre-filter ring, which is only available in the new air purifiers. This filter should be branded as permanent HEPA since it is washable.

    Thanks to its well-known popularity, many filters use the HEPA acronym, which is confusing for those looking for a "air purifier" for the first time. The only certificate mark that you can trust is "True HEPA Filter."

    A True HEPA Filter is authorized to eliminate 99.97 percent of all microscopic particles as small as 0.3 microns in size, which is the smallest particle size to get into the lungs.

    To order to carry the "True HEPA Filter" name, the product must comply with the stringent requirements set by the United States. The Energy Department.

    Certain filters that use the words 'HEPA-type' or 'HEPA-like' are inferior products to 'True HEPA Filter.' These filters can only capture particles as small as 2-5 microns, which reduces efficiency by more than 600 per cent.

    Maybe you think it's good enough, huh? Think again, please. There is no norm set in place for such words like this, you may find yourself a little bit out of using the air purifier at home if you're not careful.

    Expert tips: If you are looking for a HEPA air purifier, you should always look for a True HEPA filter certificate.

    Pros:

    • Highly effective, most toxic pollutants are captured
    • Trapped particles stay within the air filter.
    • External air filter does not emit ozone, which causes asthma and other respiratory issues.

    Cons:

    • Needs daily filter replacement in order to preserve performance
    • Will not eliminate odors and smells

    Ionic Air Filter

    Ionic Air Filter (also known as Ionizer purifier) is an air filtering device that works on charged electrical surfaces or needles. It emits a cloud of negatively charged ions into the air. Contaminants (which are positively charged ions) will then be electrostatically attracted to the charged collector plate.

    In the case of poor goods, these impurities are only allowed to fall on the floor and surrounding surfaces. This procedure removes ultra-fine particles up to 0.1 microns in size.

    The Ionic Air Filter also contains small levels of ozone with less than 0.05 ppm of ozone in order to comply with industrial health requirements.

    Expert tips: Some people have argued that the ions it generates have caused an increase in their asthma symptoms.

    Pros:

    • Maintenance free, without changing the filter
    • It can even remove some bacteria and viruses

    Cons:

    • Small amounts of ozone as a by-product that may irritate asthma and respiratory problems.
    • Will not eliminate odors and smells
    • High energy consumption

    Activated Carbon Filter

    Activated carbon filter (many brands also call Charcoal Air Filter) uses a special type of activated carbon consisting of millions of tiny adsorbent pores. This activated carbon filter can adsorb and neutralize volatile chemicals on a molecular basis (e.g. toxic gases, odors, VOCs and other chemicals).

    The filtering method does not eliminate pollutants, but rather converts them from the gas phase to the solid phase. That's why this type of air filter rarely stands alone but works in conjunction with other types of air filters, mostly HEPA Air Filter.

    Expert tips: So many high-end brands only concentrate on highlighting True HEPA Filter, they also have a Charcoal layer like this.

    Carbon filters are not used to eliminate particles that cause health issues, but instead to eliminate those that cause odors. Such filters make the home smell fresh and clean.

    Pros:

    • Can be re-used
    • The only air filter to avoid toxins, fumes, tastes and smells from pets, food, smoke, paint and cleaning supplies.

    Cons:

    • Needs additional air filters
    • Needs to be frequently changed

    UV Light Air Filter

    UV Light Air Filter (UV stands for Ultra Violet) is the most distinct types of air filters from the three types of air filters listed above. It's going to be easy for you to understand this air filter if we give you a definition of UV light.

    UV light is an aspect of the electromagnetic spectrum. It consists of all wavelengths of electromagnetic radiation, including light, radio waves and x-rays, which are arranged by frequency and wavelength.

    UV light is a special form of radiation that can not be detected by the naked eye since it is part of the invisible portion of the electromagnetic spectrum. The wavelength is, to be exact, from 400 nm (750 THz) to 10 nm (30 PHz), shorter than that of visible light.

    UV-C light in the air purifier is a strong source of radiation that does not affect people. However, it is excellent for killing microorganisms, such as germs and viruses.

    Summary: UV Light Air Filter technology emits invisible light (called Ultra Violet Light) that destroys contaminants (mainly germs and viruses). UV light is contained inside the air purifier and is not released into the room. The type of UV light (UV-C radiation) is also harmless to humans.

    When air passes through the air purifier, after all other forms of filters, it eventually passes through a small inner space that exposes the particles to UV light. The UV light air purifier works by destroying the DNA of these germs and viruses. It method sterilizes and stops them from spreading to make you ill.

    However, in order to fight against other contaminants such as dust, mold, animal dander, the UV Light Air Filter can not stand alone and must be combined with others.

    Expert tips: Always check the air purifiers using UV-C light technology. This type is completely safe for humans and does not cause any negative side effects.

    Pros:

    • It can kill microorganisms such as germs, bacteria and viruses
    • UV-C radiation does not cause damage to humans

    Cons:

    • ozone
    • Needs to be frequently changed
    • Large use of electricity
    • Can not remove the actual particles from the air
