I live near FWY and a busy street, so this one does a fantastic job in capturing air born dusts that could otherwise enter into my lungs. Do this test in a completely dark room: placing a flash light right in front of your face will show you myriads of dusts, many are disease causing, floating around in the room. When those particles entering into body, our immune system must to fight against invaders by compromising other important tasks. In my view, all air cleaners are noisy and somewhat leave a room dry but this model is by far quieter than the other leading brands I have tested. If you're looking for one in your bedroom, you may go for the model#30090 or #30095, for they're even quieter at low setting due to operating with a smaller fan and motor. I place mine in a living room running w/a timer and leave the bedroom door open during the night, which seems to be okay. (I'm noise sensitive). Tips: gently vacuum the pre-carbon filter once a month and wash the filter and rinse with purified water every 3 months will maintain its optimal performance and also extend the filter's life (new filter costs $40 @ Lowes). For years, I had been skeptical about an air cleaner but I was wrong. In retrospect I should have bought it long time ago. Oh, for the best result, you' d try the "fresh air" by Ecoquest, which eliminates odors and kills dust mites, bacteria, and viruses altogether with ozone and oxygen ions the machine produces. There's been a misconception about the safety of ozone but is in fact a good guy at the low concentration. Believe it or not, the nature produces and uses ozone to clean the air. If you want to know more about it read the book "The Silent Killer" by Pete Billac. I bought mine at eBay for much less than the retail tag.

Product Description:
The upright, three-speed Hunter Quietflo Air Purifier (30119) features a true HEPA filter element that captures 99.97 percent of particles as small as 0.3 microns in size. This whisper-quiet unit has a Clean Air Delivery Rate (CADR) that will exchange air up to six times per hour in a 14 by 14-foot room with an 8-foot ceiling. Other features include an air flow rating of 225 CFM (cubic feet of air per minute), and LED filter change reminders. It works well on the floor or on a shelf and it can be wall mounted. It maintains full effectiveness even when placed in a corner or against a wall.
The QuietFlo fan system draws air into the unit without the excessive noise associated with many competitive models. The advanced activated carbon pre-filter reduces cooking, tobacco, and pet odors at least 30 percent better than the competition, and it also captures large dust particles, lint, and pet hair. It finally exhausts clean, purified air back into the room from the top of the unit to avoid disturbing settled particles.

Laser Air Quality Monitor Review

I bought one of the Dylos monitors several months ago and I was initially quite impressed.I have the more advanced, 0.5 micron model, and it reported count readings that seemed to correlate with time of day (lower reading at night) and activity (e.g. higher reading when I am dusting) However, I was not as impressed after it started to report readings that were inexplicable.For example, after a while, the reading seem to rest on a plateau of about 2200 (which signified bad air quality), whereas before it should normally read 700.I taped a piece filter paper to cover the ingress and the reading will drop to 1700.So I called up Dylos customer and technical support, who were very friendly and helpful.However, the answers I got from them were not entirely encouraging.First, the monitor had no calibrating function.So, if you suspect the reading is too high (as in my case) or too low, you are just left wondering; and of course, once you think a test or measuring tool is suspect, you don't trust/use it!Second, both the ingress and egress of the monitor has no wire gauze to protect insects from getting inside.This is not good, because if an insect got inside and contaminated the lens, the readings would be completely meaningless.Third, worse yet, you are not supposed to open up the monitor (it will void the warranty; laser might injure your eye if you are not careful) to do any cleaning.So, if, over time, cooking grease vapor, say, condensed on the surface of the lens, the accuracy of the reading would be called into question, and you cannot do any meaningful cleaning.Dylos technical support was kind enough to check and service the monitor for me (even though I admitted to having opened the unit), but the monitor still does not work right.

So, as much as I appreciate the good folks at Dylos, who really tried to help me, I just do not find this monitor a reliable tool, due to the design flaws I outlined above, which I hope they would address in a subsequent version.I hope your experience is better.

Sharper Image Ionic Breeze 3.0 Compact Silent Air Purifier (SI397) Review

I purchased this after an informercial. My warrenty was for 3 years. Lucky for me, since 14 months after receiving the unit it died with no warning.
The manufacture made me return it AT MY OWN EXPENSE and then they sent me a new unit. Took 2 months.
Well, the new unit arrived 8 days ago. It died an hour ago. I called the customer service and refused to pay to send it back AGAIN.
They ARE sending me out a new unit (again), but it will take up to 10 business days to receive. They agreed to send a pre-paid shipping label this time too. (Could take a month though.)
Meanwhile, I have nothing. After reading the reviews below, I could have kicked myself. I subscribe to the online version of Consumer Reports so did what another did...looked it up. Consumer Reports says this Ionic Breeze only "removes a few particles from the air", nothing else. They also did the test, as the infomercial showed, of putting the Breeze in an enclosed space with smoke and turned it on. It did NOT do what the infomercial said. It did not "power through smoke". It did nothing.
I am taking the advice of Consumer Reports. I am refunding my money on the Breeze and purchasing "the high-scoring Friedrich C-90A and Whirlpool AP45030HO models" which DOES work...and work well.
Avoid the Ionic Breeze unit, for the home AND/OR the car.

Product Description:
* Room air cleaner circulates and cleans air with no motor, no fan and no noise. Key features include absolutely silent operation; proven efficient air cleaning; odor reduction; no replacement filters; low energy use; lightweight, attractive housing; continuous air cleaning. * Tests at leading research centers show that Ionic Breeze does a great job capturing particles like pollen, dander and other airborne allergens and irritants. Quadra Compact has been tested at America's leading allergy research center, prominent universities and independent labs to confirm its efficient trapping of airborne particles of one micron or larger. * Save money! There no messy, expensive filters to find, buy, store and replace. Quadra is an electrostatic precipitator that charges airborne contaminants and traps them on oppositely charged stainless steel collectors that wipe clean. Quadra Compact is powered by only 6 watts. Compared to high-watt HEPA machines, it pays for itself in less than a year. * Cleans 24-7! Turn off a noisy HEPA air cleaner and air pollution goes right back to where it started. All air cleaners should run continuously but noisy fans and expensive 200-watt power demands make that impractical with those big HEPA machines. Silent, low-energy Ionic Breeze is designed to run continuously. Plug into 3-prong outlet. * Quadra is 19" tall and 4 1/4 lbs, with almost the same cleaning power as the larger Quadra. Uses only 6 watts. * Suggested for rooms up to 270 sq. ft.
