Absolutely not! Because of our quiet fan engineering as well as multiple filtration technologies that don't put all the work on the fan to begin with, all our air purification units run quietly even when operated at high speed. For example, Ultra-Pure's 899 and 988 models generate less than 50dB (decibels) even when operated at maximum power. That's quieter than your average computer fan and only a little more than the noise a refrigerator generates.

Because Ultra-Pure uses advanced multi-stage air purification technologies including washable prefilters, HEPA filters, activated carbon, ultraviolet light, negative ions, titanium dioxide germicidal sanitizers and optional (on-off) ozone generation, we're able to filter or destroy a whole range of harmful airborne particles that old fashioned single-stage, or even 2-, 3- or 4-stage air purifiers, just can't match.

Not at all, unlike, many of our competitor's air purifiers that have exorbitant power needs which can cost you hundreds of dollars per year in electrical costs, Ultra-Pure's energy efficient systems operate on only 40 to 65 watts of power. That's less than the average light bulb and cost you only a few dollars per month even if run continuously 24-hours a day. When you purchase an Ultra-Pure air purifier you are buying direct from our parent company Real Spirit USA.

Air purifiers remove airborne particulate from the air. Air is drawn through the filter and particles are trapped in the filter system. The filtered air is then re-circulated back through your home.

Air purifiers take out a lot of the pollutants from our air which can irritate allergies and asthma. These pollutants include airborne particulate as small as 0.3 microns and includes pollen, dust, pet dander, mold spores and smoke.

Generally every 2 - 3 months, but you may want to change them more often. During periods where you are using your HVAC system continuously, we recommend changing monthly to maintain the best indoor air quality. The following chart should assist you: quot;The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace your air filters[..

Depending on the fan setting used, the noise level ranges from less than 50 to 65 decibels, or from the sound of a whisper to the sound of a normal conversation. No. Austin's Air cleaners do not produce ozone, ions, or negative ions. Ozone is active oxygen and can be dangerous to people's health. This is especially true for people with respiratory problems such as asthma emphysema, and bronchitis.

The manufacturer's warranty varies from manufacturer to manufacturer. They range from one to ten years. Each manufacturer's warranty is clearly marked on each individual product page.

Microban is used in air purifiers because it is an Antimicrobial agent used to treat an air purifiers HEPA filter. The protection provided by the Microban product prevents development of mold, bacteria or mildew growth on the filters surface which can cause bad odors. The life expectancy of your filter is not affected by the Microban.

Only certain ionizer air purifiers have ionizers built in. Unless the air purifier specifically states that it is has an ionizer it is more likely to use a mechanical filter instead.

Biozone? air purifiers make about the same amount of noise as the average computer fan, much less than a micro-wave or air conditioner, and slightly more than a toaster. Our air purifiers use a very quiet 3 speed fan, similar to a computer fan, this pulls enough air through the air purification chamber at a rate that creates optimum levels of purifying plasma. If sound level is an issue, select a slightly more powerful air purifier and run it at a lower speed.

The inlet grill draws in dirty air. In most HEPA air purifiers, a washable pre-filter traps larger particles. By definition, a HEPA filter removes at least 99.97% of all particles as small as 0.3 microns. HEPA air purifiers were originally developed by the Atomic Energy Commission to capture radioactive dust particles. Allergens such as pollen, animal dander, mold spores, and dust get trapped in the filter.

Some air purifiers, such as the Blueair units, are extremely quiet, while others can be quite loud when operating at high power. If possible, ask for a demonstration before you buy your air purifier. Also, please see our Air Purifier Noise Graph.

We offer a wide variety of air purifiers designed to treat a number of indoor air quality problems. There are many factors to consider when shopping for an air purifier, but the main factor to consider is the type of pollution which you're trying to eliminate. See our Air Purifier Buying Guide for more information about what you should consider before buying and air purifier, and see our Air Purifier Comparison Chart for an in-depth look at the differences in our air purifiers.

The air filters generally ship within 4 to 10 business days. If you order a Custom Size Air Filter, we generally need from 10 days to 2 weeks to manufacture your custom air filter plus delivery time. AC Filter shipping is by UPS Ground from Celina, TX or Tulsa, OK. Time in transit will vary. We cannot ship to P.O. Boxes. You will receive an email with your tracking number from UPS Quantum View when your package ships.

Virtually all apartments provide air filters for their tenants. Normally, cost is the primary consideration given to air filters for HVAC systems. As a consequence, you are not likely going to get the best air filtration possible. We recommend you contact the Property Manager and explain your desire to obtain a higher-quality filter in your HVAC system.

Nordic manufactures all of our air filters using a filter media that contains a permanent electrostatic charge causing dust to cling to the air conditioner furnace filter using the same principle as static electricity. As a consequence, our air filters are far more effective and efficient than traditional pleated filters. Nordic does not endorse or sell the permanent metal electrostatic filters.

Nordic Pure Merv 12 filters have a low air flow resistance for residential and commercial heating and cooling systems. Air flow is generally measured as a difference in air pressure on each side of the filter, measured by an instrument that uses water in a measured column to show air pressure. The higher the pressure difference, the more the water in the instrument moves. Its movement is measured in inches. The more inches of water moved, the more the pressure difference.

Biozone? air purifiers can remove contaminates down to .01 microns, much smaller than even the best medical grade hepa filter! Biozone? air purifiers are capable of removing hazardous chemical fumes, viruses, bacteria, germs, allergens, pet dander, cigarette smoke and fumes and almost anything you can imagine, from the air. This is a pretty bold statement. Maybe as bold as our 90 day money back guarantee!
