It doesn't require much space. The size (25.5" high x 11.5" deep x 7" wide) is suitable for my bedroom and the location I had in mind.2. I wanted an air cleaner that does not require costly replacement filters. The Pure-Ion Pro contains one single filter which is designed to be used for the life of the product. I wash the filter under a shower aided by a tub & toilet spray cleaner. A flashing LED signals when a wash is due.*The filter is a principal part of the unit and must be protected at all times. An impaired filter will impede your unit. Consequently, DO NOT WASH YOUR FILTER IN A DISHWASHER. Although the idea of it may sound convenient the reality is going to be somewhat different. For instance: (1) Your filter can be damaged as you lower it onto the loading rack. (2) Even if the filter is alone in the dishwasher bits of food (debris from previous washes) can adhere to the filter and "cement" there during the drying cycle.

(3) Still worse, callously placing the filter among dirty dishes will surely subvert the filter even quicker. Been there, done that and had to exchange my unit for a new one.3. I wanted an air cleaner with three fan speeds. This one has five. There's WHISPER, LOW, MEDIUM, HIGH and TURBO. Quite obviously, this sleek product contains all the bells and whistles.4. I wanted an ion emitting air cleaner. Press the ION button atop the Pure-Ion Pro and an LED illuminates letting you know that the ION function is activated.5. I wanted a quiet device that would allow me to fall asleep. On WHISPER setting I can still hear the fans, but the sound is minimal enough so as not to be a problem. It was surprising to us that at bedtime my wife and I actually prefer MEDIUM speed. The sound is not the type of sound to keep us awake.6. The unit has an automatic timer which I use occasionally. Choose 2, 4, 6, 8 or 12 hours of operation.This air cleaner has definitely made a difference. We breathe through the night with clear nasal passages.

My wife has asthma and is greatly relieved, more so than with our previous air cleaners which embodied the HEPA filtration technology. kenmore air purifier 85500(HEPA: High Efficiency Particulate Accumulation).air purifier novita nap 101Brookstone's Pure-Ion Pro cleans the air in two ways: Besides catching dust and allergens in its filter, the continuous emission of negative ions bring airborne contaminants to the ground. airfree e40 air purifier reviewsConsequently, you may need to vacuum and/or dust a bit more often, but considerably less irritants shall find sanctuary in your air. As I alluded to in #4 (above), the ion emitter can be turned on or off at your discretion.Detractors of ion emitting devices point to the fact that they produce unwanted ozone.

I tested the Pure-Ion Pro with an ozone detector card from Ozone Solutions of Hull, Iowa. Finding absolutely no visible reading I contacted Brookstone in this regard. I was informed that the Pure-Ion Pro produces less than .05 parts per million of ozone (well within the limits of Federal EPA, California EPA and FDA standards) and would therefore be detectable only on the most sophisticated detection equipment.Detractors also claim that walls will soon become filled with dust. Well, after eight months I have yet to find any, but I promise to keep an open mind and will update if I do.For those who are skeptical about what they cannot see, an "Ion Stick" is available for ion testing. Ion Stick(TM) I tested the Pure-Ion Pro on MEDIUM speed holding the Ion Stick two feet off the front grille. Readings fluctuated widely and rapidly in the air flow, but the highest reading I caught was in the 1,900's; this was on the Ion Stick's scale from "000" to "1,999".Brookstone's Pure-Ion Pro has not disappointed.

An excellent product made in China.For further information about air purifiers in general I would suggest Consumer Reports Magazine. Consumer Reports (1-year auto-renewal) See also, on line, "Consumer Reports: Expert product reviews and product Ratings..."*I've been using Soft Scrub or Fantastik. I spray generously into the filter and allow the chemicals to work. Then, after a minute, I shower the filter clean. I turn it over and repeat until water destined for the drain is without residue.But, be careful when cleaning filter!Solved my wife's allergy problems literally overnightLoved It!Pro air cleaner Pure-Ion Bedroom™ Air Purifier and Humidifier Trap dust & pollutants in washable filter De-humidification makes air more comfortable Timer runs 2 to 12 hours or continuously Whisper quiet for use in bedroomsThe May issue of Consumer Reports presents new concerns about ionizing air cleaners: among five models that did a poor job of cleaning the air, several can expose users to potentially harmful ozone levels.

Months of unbiased testing and expert investigation demonstrate why the five ionizing models with poor performance, including those with relatively high ozone generation, are not recommended.Ozone from ionizing air cleaners is a growing concern as sales increase. People with asthma or respiratory allergies are especially sensitive to indoor ozone, an irritant that can worsen asthma, deaden sense of smell, raise sensitivity to pollen and mold, and may cause permanent lung damage.CR tested ionizing air cleaners for ozone levels and for their ability to remove dust, cigarette smoke, and pollen from the air. According to CRs independent test results, the following models are not recommended because they perform poorly and emit relatively high levels of ozone:• Brookstone Pure-Ion V2; • Sharper Image Professional Series; • Ionic Breeze Quadra S1737 SNX; • Ionic Pro CL-369; and • Surround Air XJ-2000.All five ionizers failed the industry standard sealed-room test for ozone levels replicated for this report by producing more than 50 parts per billion (ppb) of ozone near the machine.

This limit is used by manufacturers who submit their air cleaners to a voluntary standard that includes a test to measure ozone levels in a sealed room.In further CR tests within a well-ventilated open lab, the IonizAir P4620 and the Surround Air XJ-2000 emitted more than 150 and 300 ppb of ozone, respectively, near the machine. While readings were far lower 3 feet away, consumers could be exposed to higher ozone levels than those CR measured at 3 feet if they take a cue from manufacturers.On their packaging, some manufacturers show these machines near a sleeping person, close to and facing a sofa, or on a desk near a keyboard. One manufacturer recommends putting its model near those suffering from breathing or other health problems.If you own one of the five poor performing ionizers, CR suggests trying to return it for a refund.However, not all air cleaners produce significant amounts of ozone. The top-performing Friedrich C-90A, an ionizing electrostatic precipitator model, is very effective and emits little ozone.

Another fine performer that emits little ozone is the Whirlpool 45030, which is a HEPA-filter model.How CR tested ionizing air cleaners for ozone levels: CR replicated the test used by manufacturers by using a sealed polyethylene room specified by Underwriters Laboratories Standard 867. Ozone levels were measured 2 inches from each machines air discharge in accordance with the standard. Because people dont live in sealed plastic rooms, CR also tested these ionizing air cleaners in an open well-ventilated lab. In this test, CR measured ozone levels 2 inches from the machines, as it did in the sealed room test, and 3 feet away, since ozone becomes diluted and dissipates rapidly indoors.About the risks of indoor ozone: Ionizers now account for about 25 percent of the roughly $410 million per year spent on air cleaners. Experts agree that an ozone concentration of more than 80 ppb for eight hours or longer can cause coughing, wheezing, and chest pain while worsening asthma and deadening sense of smell.

A 14-year study of 95 urban areas in the U.S. found a clear link between small increases in ozone and higher death rates. The study, which appeared in the November 2004 Journal of the American Medical Association, predicts that a 10-ppb increase in ozone over eight hours could lead to roughly 3,700 premature deaths per year in some cities.While ozone dissipates indoors, it can create other pollutants in the process.Air cleaners need not meet ozone limits - not for the Environmental Protection Agency, which regulates only outdoor air, nor for the Food and Drug Administration, since it does not consider them medical devices. No federal agency sets indoor ozone limits for homes.The Consumer Product Safety Commission is reviewing data on all air cleaners that create ozone and is evaluating whether the 50-ppb industry standard is adequate protection for consumers.Recommendations: Consumers Union, the independent, nonprofit publisher of CR, believes that the Consumer Product Safety Commission should set indoor ozone limits for all air cleaners and mandate performance tests and labels disclosing the results.
