Guardian Technologies™ has you covered in providing the air filter best suited to your particular living situation. All of our Air Filters are either: HEPA-Type, True HEPA or Pet Pure® HEPA, each with their particular benefits.
How Do Air Filters Work?
- Air filters remove airborne and particulate matter such as dirt, allergens, bacteria, dust and smoke from the air.
- Air filters work by pulling “dirty” air through a filter and trapping the particulate matter.
HEPA-Type Filters vs. True HEPA
- HEPA stands for High Efficiency Particulate Air, and is one of today's top trusted air purification technologies. Through tightly woven material, it captures airborne particulates as small as 0.3 microns in size, such as dust mites, debris, mold spores, pollens and pet dander.
- Particles that can trigger asthma or allergies typically range from 1.0–10.0 microns in size, and pesky bacteria particles around 0.3 microns in size. HEPA technology makes it possible to remove particles as small as 0.3 microns — making it a highly effective solution to remove potentially harmful particles from your indoor air.
- To be considered True HEPA by DOE (Department of Energy) standards, an air filter must remove 99.97% of all airborne particles as small as 0.3 microns in size. Using a True HEPA air filter is the most effective way to remove odor-producing bacteria, as well as minuscule irritants that can cause allergy and asthma symptoms.
- True HEPA filters are highly effective to address your clean-air concerns. We recommend it as the most effective solution to protect you against dangerous airborne particles.
What Is a Pet Pure™ True HEPA Air Filter?
- Whether you have pets in your home or spend a substantial amount of time around animals, animal dander can be a large contributing factor to respiratory issues or odor-producing bacteria.
- Pet Pure™ True HEPA filters are treated with an anti-microbial agent to inhibit the growth of mold, mildew and odor-causing bacteria on the filter itself. The Pet Pure™ filter treatment results in better air filtering, especially with regard to pet odors.
How Often Should an Air Filter Be Changed?
- We recommend you change your filter every 6–8 months.
- Like other consumables, life span of a filter is based upon usage. Our air purifiers are built for constant daily use. If you use yours less frequently, your filter will last longer.
- You can usually determine whether you’re ready to change the filter based upon its appearance. If it appears dirty, it should probably be replaced as soon as possible. See our Replacement HEPA and True HEPA Filters.
