20x20x2 Day and Night Carbon/Potassium Air Purifier Filter

Indoor air pollution is just as harmful as outdoor air pollution and can lead to and worsen respiratory problems, asthma, bronchitis, and other health conditions. Indoor air pollution is caused when too little outdoor air is allowed to circulate throughout the home. This causes air pollutants such as dust, pollen, pet dander, smoke, chemicals and gases to accumulate within your home. Volatile organic compounds (VOCs) are chemicals found in everyday household products such as paints, cleaning supplies, and air fresheners. VOCs evaporate into the air when they are used and even when they are in storage, and they can cause damage to the liver, kidneys, and central nervous system, and some can even cause cancer.

VOCs, as well as odors and other chemicals/gases, are smaller than 0.01 microns. Regular air purifier filters, even HEPA filters, are unable to trap VOCs. Carbon, when activated with oxygen, is able to trap these extremely tiny pollutants, but regular carbon filters are only able to do so in relatively small quantities. The thicker the carbon filter, the more efficient that filter is. Chemical air purifiers work by binding gases to a carrier and breaking down those gases through oxidation. The best VOC-capturing filters have a carbon/potassium permanganate mix. This creates a highly porous filter and a powerful oxidizing ability.

This 20x20x2 Day and Night air purifier filter is a replacement filter for whole house air purifier filter model P102-550. It is a carbon/potassium air purifier filter, which means that it is highly efficient at removing harmful gases, chemicals, and odors. Its carbon web flexible carbon filled fibers help it last longer. This air purifier filter measures 19.5" x 19.5" x 1 3/4" and must be changed every 6 months for highest quality filtration.
