Oransi V HEPA Plus Air Purifiers (Model OVHP44)

How the v-hepa plus air purifier cleans the air:

Pre Filter: The air first enters the pre-filter, capturing the largest particles, which enhances the durability and performance of the HEPA filter
High-Efficiency HEPA Filter: Effectively removes up to 99.97% of airborne particles that pass through the system, including contaminant particles such as pollen, bacteria, dust mites, viruses, smoke, and other airborne impurities as small as 0.3 microns. Unique low air flow resistance technology makes the air purifier more powerful and effective.
Patented and Effective Ionizer: The nano piezo-electric ion makes your room more like a natural environment. A Journal of Hygiene study found negative ions to improve efficiency of filter units and multiple studies (including those by the U.S. Dept. of Agriculture) have found it to be highly effective against dust and bacteria.
Photocatalytic Oxidation (PCO) Filter: This filter is coated with titanium dioxide, which produces highly reactive ions and electrons when combined with the UV light from the UV-C lamp. These highly reactive ions attach to chemical molecules, bacteria and odor-causing compounds, destroying them through oxidation.
Germicidal UV Lamp: The most effective way to destroy micro-organisms, such as germs, viruses, fungi (such as mold) and bacteria. Also destroys micro-organisms including those that are trapped by the HEPA air filter, preventing them from reproducing and recirculating through the room. UV lamps are recommended by the U.S. Centers of Disease Control. Replace annually for best results.

Pre-filter should be washed or vacuumed every 2-3 months depending on indoor air quality. HEPA filter life is 5-6 months if operated continuously and 10-12 months if operated intermittently. Life span of HEPA filter depends on air quality and usage. PCO filter is permanent. UV Lamp should be replaced annually to ensure top performance.

Summary:

Going into our testing, we were skeptical of this new little air purifier as we are with most new air purifiers on the market. However, it quickly put a smile on our faces as our particle counter showed the filtered air coming out of the V-HEPA Air Purifier was 98% cleaner than the air in the room prior to turning it on. We were even more impressed when we found out that this small air purifier could clean a room up to 240 sq. ft. with 5 air changes per hour! Its simple design made it very easy for us to access the filters and operate it without needing to look at the manual, which is great for someone who wants a no-fuss air purifier. While on, it produced a quiet hum and was tolerable on all 3 speeds. We also like the fact that the company has a 'green' focus and a complete list of the safety certifications. It does have a PCO filter which works with the UV lamp to help neutralize light gases and odors, but it is not as effective as activated carbon at removing chemicals, gases and odors. Therefore, we recommend this unit for someone who is primarily concerned with removing allergens and other irritating airborne particles from their bedroom, office or small family room.
