Mold, pollen, dust, bacteria, pet dander
The v-hepa Max air purifier cleans the air so you can breathe better, sleep better and feel better to be your best. You get high-end air purifier performance and a shrewd buy that works with your budget in mind. Besides a washable pre-filter and 99% HEPA filtration you get an activated carbon filter for light odors and gases.
The v-hepa MAX is our best air purifier and we've redesigned the filters to make them larger and improved upon the seals to ensure you get the cleanest air possible. Larger filters means they can be used longer (12 months of continuous use). The v-hepa Max air purifier does it all to clean the air so you can breathe better, sleep better and feel better to be your best. Designed for rooms up to 600 sq ft (20' x 30'). You get high-end air purifier performance and a shrewd buy that works with your budget in mind. Besides a vacuum-able pre-filter and v-HEPA filtration for dust, bacteria, pollen, mold, and pet dander, you get a large activated carbon filter for light odors and gases, negative ion, dust sensor, and room air quality display.
Simple to use, low cost to operate and quiet compared to competitive air purifiers (v-hepa Max at 34dB to 53dB as compared to 60dB-70dB).
Pre Filter: The air first enters the pre-filter, capturing the largest particles, which enhances the durability and performance of the other filters.
High-Efficiency v-HEPA Filter: The most effective type of air filter at capturing dust, allergens and other solid particles (including bacteria). Effectively removes up to 99% of airborne pollutant particles that pass through the system. This includes contaminant particles such as pollen, bacteria, dust mites, viruses, smoke, and other airborne impurities as small as 0.3 micron. Unique low air flow resistance technology makes air purifier more powerful and effective.
Activated Carbon Filter: The best type of air filter for trapping chemicals, gases, odors and cigarette smoke. We've doubled the size of the carbon filter making it the best in class of air purifiers. According to Penn State Dept. of Aero-biological researchers, carbon filters serve to remove odors, volatile organic compounds (VOCs) and chemicals that other filters cannot.
Anion: The nano piezo-electric ions 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 to be highly effective against dust, bacteria, etc.
Night Mode: Don't want a bright light shining at night? Press and hold the power button for 3 seconds and the light around the power button will turn off. Press and hold the power button for 3 seconds to reactivate this light. Note: the blue lights in the center display (ie fan speed display) will remain illuminated but they are not very bright.
Intelligent Air Quality Monitor: gives you a visual indication of the air quality in your room from the front of the air purifier. If operated in auto mode the air quality monitor will adjust the fan speed depending upon the air quality reading. When first started the sensor may flash "AQS" for the first ten minutes. This is to indicate that the Air Quality Sensor is warming up and calibrating.
Troubleshooting: If the air purifier does not power on, remove the front cover and the filters and re-insert each. We have a safety switch that ensures that the cover is completely closed and in shipment the cover may open slightly. Also, if you press the Auto button, the fan speed display will reflect the air quality reading and not the current operating fan speed so there can be a difference. We suggest setting the fan speed where you would like it and then press Auto. If the sensor shows 0 or 1 bars the fan speed will show as Silent, 2 bars is Middle, 3 bars is Strong and 4 bars is Turbo.
