According to the Environmental Protection Agency (EPA) most homes are 2 to 5 times more polluted than outdoor air. And many homes have as much as 100 times more pollution than the worst outdoor air.These are sobering stats and one of the reasons many Northern California homeowners are looking for whole-home air cleaners.But shopping for the right air cleaner can be confusing. In this article, we’re going to look at two types of whole-home air cleaners (sometimes called air purifiers)  – UV air cleaners and HEPA air cleaners.UV stands for ultraviolet. These air cleaners use UV light to kill harmful microorganisms like mold, viruses and bacteria.What it does: A UV air cleaner is installed over your air conditioner’s coils to kill mold and bacteria that can collect there.Why it’s needed: Your coils are cold, which causes water from your air to condense on them. This creates a moist environment where mold and bacteria can grow. The bacteria and mold spores can then be carried into your home through your ductwork.

Get a UV air cleaner if:HEPA stands for high-efficiency particulate air. What that really means is that these filters remove even very, very small airborne particles. (Read more about how small airborne pollution is and why it matters) HEPA filters are used in hospitals and clean rooms because of their ability to clean indoor air.What it does: A HEPA whole-home air cleaner is essentially a very fine air filter (actually a series of very fine filters) and a fan. The fan pushes the air through the filters, removing 99.97% of all indoor air pollution down to .03 microns. Some HEPA air cleaners also have a UV light built in to help kill mold, bacteria and viruses.Why it’s needed: As we said in the intro to this article, most homes are much more polluted than the worst outdoor air. And many of the common pollutants in homes have serious health effects. A HEPA whole-home air cleaner is the best home air filtration available.Get a HEPA air cleaner if:Of course there are many other air cleaning options available to Northern California homeowners today, these are just a couple we get the most questions about.

There are also whole-home air cleaners that aren’t quite as powerful as HEPA air cleaners, but offer some of the same advantages.Want more information on what’s right for your family?

When placed over the air conditioning coil the UV-Aire is our pure air solution that eliminates mold build-up and keeps your system running more efficiently. Mounted inside the ductwork, the UV-Aire sterilizes or kills most contaminants as they pass the lamp.air purifier kolkata Our in-duct models work with your forced air system 24/7 and our portable models provide added protection in bedrooms, living rooms and kitchens, wherever you need it most.harley evo air cleaner cover The process requires very little maintenance and costs just pennies a day to operate. air purifiers whole homeThe UV-Aire could be one of the best health and comfort investments a homeowner ever makes. Kills and reduces airborne germs, bacteria, viruses, mold, and fungi

Eliminates mold growth on air conditioning coil Prolongs the life and maintains efficiency of the equipment The right model for virtually any heating system Since the first UV irradiation system was used, the disinfection of medical equipment using UV has been a common and reliable practice. UV disinfection has been determined to be adequate for inactivating bacteria and viruses The germicidal effects of UV light cause photochemical damage to DNA and RNA within microorganisms. “...ultraviolet radiation, properly integrated with heating, ventilating, and air conditioning systems, shows the most promise as a widely applicable means of air disinfection.” UV-Aire uses the energy from a specially designed, high-intensity UVC germicidal lamp to reduce microorganisms in the entire home as they cycle through the HVAC system. The UV-Aire could be one of the best health and comfort investments a homeowner ever makes. UV’s effectiveness in killing bacteria is directly related to the microorganism’s exposure time.

Indoor air in a typical residential forced-air HVAC system will be recirculated 40-75 times a day. With a UV generating lamp mounted in the HVAC duct, cumulative exposure can be very effective in controlling indoor bacteria and other airborne containments. UV rays will also kill germs and mol that breed in drain pans and A-coils. Properly positioned, an ultraviolet system can significantly reduce indoor air contamination and prevent the growth of new microorganisms.

"The things that were important to me—the freshness, the cleanliness of the air—I was able to sit down with the builder and figure out which components would deliver those for me. The new house smell has stayed with us. The odors don’t linger; I don’t notice a smell when I’m done cooking." — Tracy Martin, Greenville, NCJ Occup Environ Hyg. 2006 Oct;3(10):536-46.Kujundzic E1, Matalkah F, Howard CJ, Hernandez M, Miller SL.

Author information1Department of Civil, Environmental and Architectural Engineering, University of Colorado at Boulder, Boulder, Colorado 80309-0427, USA. shelly.miller@colorado.eduAbstractIn-room air cleaners (ACs) and upper-room air ultraviolet germicidal irradiation (UVGI) are engineering control technologies that can help reduce the concentrations of airborne bacteria and fungal spores in the indoor environment. This study investigated six different types of ACs and quantified their ability to remove and/or inactivate airborne bacteria and fungal spores. Four of the air cleaners incorporated UV lamp(s) into their flow path. In addition, the efficacy of combining ACs with upper-room air UVGI was investigated. With the ventilation system providing zero or six air changes per hour, the air cleaners were tested separately or with the upper-room air UVGI system in operation in an 87-m3 test room. Active bacteria cells and fungal spores were aerosolized into the room such that their numbers and physiologic state were comparable both with and without air cleaning and upper-room air UVGI.

In addition, the disinfection performance of a UV-C lamp internal to one of the ACs was evaluated by estimating the percentage of airborne bacteria cells and fungal spores captured on the air filter medium surface that were inactivated with UV exposure. Average airborne microbial clean air delivery rates (CADRm) varied between 26-981 m3 hr-1 depending on the AC, and between 1480-2370 m3 hr-1, when using air cleaners in combination with upper-room air UVGI. Culturing, direct microscopy, and optical particle counting revealed similar CADRm. The ACs performed similarly when challenged with three different microorganisms. Testing two of the ACs showed that no additional air cleaning was provided with the operation of an internal UV-C lamp; the internal UV-C lamps, however, inactivated 75% of fungal spores and 97% of bacteria cells captured in the air filter medium within 60 min.PMID: 16908454 DOI: 10.1080/15459620600909799 [PubMed - indexed for MEDLINE] Publication TypesComparative StudyEvaluation StudiesResearch Support, Non-U.S. Gov'tResearch Support, U.S. Gov't, P.H.S.MeSH TermsAerosolsAir IonizationAir Pollution, Indoor/analysisAspergillus/physiologyDisinfection/instrumentationDisinfection/methodsDisinfection/standardsEquipment and Supplies/microbiologyEquipment and Supplies/standardsInfection Control/instrumentationInfection Control/methodsInfection Control/standardsMicrococcus luteus/radiation effectsMycobacterium/radiation effectsSpores, Bacterial/radiation effects*Spores, Fungal/radiation effects*Ultraviolet Rays*Ventilation/instrumentationVentilation/methods*Ventilation/standardsSubstancesAerosolsFull Text SourcesTaylor & FrancisIngenta plcOther Literature SourcesCOS Scholar Universe
