Recommended based on trying 5 different purifiers, Updated,

This review is from: Winix WAC9500 Ultimate Pet True HEPA Air Cleaner with PlasmaWave? Technology (Misc.)
Customer review from the Amazon Vine™ Program (What's this?)
Over the past several years, I have been on a search to find the best reasonably priced bedroom air purifier - one that works but doesn't cost a small fortune. I will give you the basics on my experience with the Winix WAC9500 and then you can see how I rank it against other purifiers I have tried. I have tried the Winix WAC9500 for only one week before writing this review, however I will update this review as my experience with the purifier proceeds.
A little background about the environment where the purifiers were used: I have had a little more than 4-years of experience with four other purifiers besides the Winix WAC9500, all shown below. All of them were used in a medium-sized bedroom in a dusty environment. Except for the Whirlpool, which I used for 3 years in a downtown city-environment with a busy street outside my window, all of the others were used in dry, dusty, desert-environments with the grand title of having nearly the worst air in the country. Plus there is a cat living in the house (mostly the bedroom where the purifiers have been located). If a purifier can control my allergies (sneezing, very watery eyes, sometimes a sore throat) from the bad air and eliminate any odors made by the cat, I know it is working. Winix WAC9500 *My overall grade: A *Replacement filters: $$$ *Replacement needed: Annually *Overall annual cost of filters: $$ Notes: I have not replaced this filter yet, but the above information is provided to compare this purifier's filters to others I have had to replace below. *Effectiveness: A *Deal breaker: Includes a remote, which is a really nice feature. The most effective, quietest, and cost-effective purifier I have found. Consumes only 15 watts on high. ******************************************************************************************* The Winix WAC9500 purifier is superior to almost any other air purifier I have tried. The closest comparison I can find is to the Surround Air XJ-3800 Intelli-Pro Air Purifier. Both of them have pretty good odor control, however I think I found that the Winix WAC9500 has superior odor and dust DETECTION. While both do pretty much the same with the odors once they are detected, the Winix WAC9500 was better at detecting odors and kicking up the fan speed in "auto mode" to eliminate them. I think I have found that the Winix may have the slight upper hand at eliminating the odors more quickly, but this advantage may come from the better and faster odor detection. As for noise, I think the Winix is slightly better than the Surround Air XJ-3800. The "high" setting on the Winix, which is less powerful than the "turbo" mode available, is quieter than the highest setting on the Surround Air XJ-3800, yet it seems just as effective at cleaning the air. The Winix WAC9500 has better fan settings. For me, there is barely a noticeable difference between the "low" and "medium" settings. One area where both the Winix and Surround Air purifiers lack is in the "auto" mode. In "auto" mode, the purifier detects dust and odors and adjusts the purifier to handle the smell or "contaminated" air. But there is inherently a defect in the way that this is designed. The purifiers automatically move to the lowest setting once the air cleaned. This by design reduces the amount of air that is moved. This affects how quickly the purifier can draw new "contaminated" air to determine that it needs to kick up the fan speed to handle the new "contaminated" air and clean. The result is dirty air in one part of the room until the purifier can draw enough of it over to the purifier to detect that it needs to increase fan speed. It takes a long time if the purifier moved to the "low" setting in "auto" mode. It would be a much better if they allowed you to set "auto" mode to the "medium" speed and it would kick up a notch or two when it senses dirty air. Because this is not possible, I have found that we tend to keep the purifiers on high, except for nights when peace and quiet is desired. Set this way, the purifiers are most effective at cleaning the air, but they consume more energy than the "auto" mode - it's a trade off. The energy efficiency of the Winix WAC9500 signficantly outperforms the Surround Air XJ-3800. The high setting on the Winix (which I believe is as efficient as the high setting on the Surround Air) uses only 15.5 watts versus 45 watts. These numbers came from a Belkin Conserve Insight F7C005q Energy-Use Monitor: Setting/ Winix WAC 9500 / Surround Air XJ3800 Low/ 6 watts / 31 watts Medium/ 10 watts / 35 watts High/ 15.5 watts / 45 watts Turbo/ 64.5 watts / 55 watts Pretty amazing that the high on the Winix WAC9500 only draws slightly more than a 60-watt equivalent CFL. There is an "auto sleep" feature on the Winix WAC9500 that I was never able to get to work correctly. Once activated, it is supposed to set the purifier on low mode when the room is dark and return to the previous settings once the room gets light again. However, every time I activated the "auto sleep" function, the purifier just went to the lowest setting regardless of how much light was in the room (I removed all of the plastic films from the front of the purifier). I think it may need a better light sensor for it to work as designed. The shipping information on Amazon indicates that the purifier is over 50 lbs., however, the actual weight of the purifier is more like 20 lbs. ******************************************************************************************* Other notes about purifiers in the same category I have tried before the Winix WAC9500: The first purifier I tried five years ago was this model based upon a Consumer Reports top pick: Whirlpool AP45030K Whispure Air Purifier, HEPA Air Cleaner (used for 3 years) *My overall grade: C *Replacement filters: $$$ (you have to buy HEPA and pre-filters separate) *Replacement needed: pre-filters every 3-4 months, HEPA every year *Overall annual cost of filters: $$ *Effectiveness: C *Deal breaker: No means to eliminate odors, while the Winix WAC9500 and Surround Air XJ-3800 have electronic odor control (which really work), and the filters became stale before the annual filter change. Required frequent vacuuming of the pre-filter. A lot of unsightly dust would accumulate on the grille, which the Winix WAC9500 and Surround Air XJ-3800 do not have. Two - Hunter 30067 Hepatech Air Purifier for Medium-Size Rooms (placed on opposite sides of the room) (used for 6 months) *My overall grade: D *Replacement filters: $$ (you have to buy HEPA and pre-filters separate) *Replacement filters are cheap and thin. *Replacement needed: after 3-4 months I found that even though these purifiers have a pre-filter, the HEPA filter was filthy and the indicator indicated that they needed replacement after only 3 months of use. (This model does not have an automatic dirty-filter alert. You have to look to see how dark the filter is and compare it to a strip on the filter.) *Overall annual cost of filters: $$$ *Effectiveness: C *Deal breaker: Noisy because we had to run them on high to be effective. Medium-speed was better as far as noise, but not effective at cleaning the dust. One of the two started to make a terribly annoying whirling-sound not even 3 months after starting to use it. We had to keep that purifier on low. These purifiers also have no means to remove odors. Required frequent vacuuming of the pre-filter. Having to replace the HEPA filter and pre-filters every 3-months was excessive and costly. Dust would also accumulate on the front grille. Rather than deal with the warranty for the defective purifier, we changed to the 3M below (for worse). 3M Ultra Clean Bedroom Air Purifier - FAP02-RC (used for 2 months) *My overall grade: F *Replacement filters: $$$ (only one filter to change; contains no other filters) Replacement filters are cheap and thin. *Replacement needed: after 3 months Since there is no pre-filter, this purifier requires more frequent replacement of the HEPA. *Overall annual cost of filters: $$$ Notes: The replacement filters were nearly impossible to find. I bought this purifier because others said they could find the filters at Target, but I couldn't. On Amazon, the filters are only available through third-party sellers. No effective means of odor elimination like the Winix WAC9500 or Surround Air XJ-3800. One single thin filter and that's it. *Effectiveness: D *Deal breaker: The single-filter design is so antiquated. The fact that dust, which would normally get trapped by a pre-filter ends up in the main HEPA filter, decreases the life of the HEPA significantly. Don't waste your time with this purifier...you'll just be purchasing countless filters. Surround Air XJ-3800 Intelli-Pro Air Purifierr (used for 6 months) *My overall grade: B *Replacement filters: $ (you only have to buy one filter - the HEPA; all others are washable) *Replacement needed: after one year *Overall annual cost of filters: $ Notes: The lights on the front of the unit are terribly bright at night, unlike the Winix WAC9500, which dims in "sleep" mode. We ended up putting black electrical tape over the lights... Read more ›

Pure Air and Amazing Filtering Techniques!,
By Martin A Hogan "Marty From SF" (San Francisco, CA. (Hercules)) - See all my reviews (VINE VOICE) (TOP 500 REVIEWER) (2008 HOLIDAY TEAM) (HALL OF FAME REVIEWER) (REAL NAME)
This review is from: Winix WAC9500 Ultimate Pet True HEPA Air Cleaner with PlasmaWave? Technology (Misc.)
Customer review from the Amazon Vine™ Program (What's this?)
In the past, I've used various air purifiers, mostly due to my cat's dander and occasional odors (like burning something in the kitchen). Holmes HAP716-U True-HEPA 3-Speed Tower Allergen Remover was convenient and had a thin washable piece of foam, but expensive filter replacements. I used to actually vacuum out the filters to make them last. This Winix True HEPA Filter is an amazing machine.
The Winix cleans through five stages instead of two. Air is also pulled in from two opposing sides with 1" gaps instead of one side and shoots it straight up into the room. The air first travels through the "washable" Anti-Bacterial Pre-filter, then the True Hepa Filter, the "washable" cassette frame, then the "`washable" Nano-Silver Mesh, then the "washable" Carbon Filter before finally getting a dose of `PlasmaWave', which generates both positive and negative ions to create plasma clusters. This neutralizes viruses, bacteria, chemical vapors and odors. Since this is the Ultimate Pet Model, it actually SUCKS CAT HAIR onto the first "washable" Pre-filter! This is what I have always been looking for. The Display Panel is very intuitive with a timer button, a function button (low, medium, high and Turbo), Dust & Odor Sensors which actually will rise on a colored grid from green to yellow to red. One day, I burned bacon in the kitchen and the Odor Sensor went into red, even though it was in the next room! The Change Filter Indicator lets you know when it is time to clean your "washable" filters. In Auto-Mode, the `smart sensors' sense the amount of impurities and adjust the fan speed accordingly! The entire unit will go into `sleep mode' when the room is dark, providing filtration without any noise and will readjust with light. There is a sensor for everything. I like the medium setting for sleeping, providing a low white noise. This is a sturdily built HEPA filter and with washable filters, it will last and save you money. The only filter that needs to be changed is the True HEPA Filter and these run about eighty dollars, but I do not anticipate changing this often considering moderate use of three months only suggests cleaning the washable filters. Considering I sneeze violently at least once a day, I have not had an attack since this machine has been turned on. This unit is a keeper. (I even suspect that when the True HEPA Filter needs to be cleaned I could use my vacuum, but we'll see how long that takes). There is also a nice small remote control that works all functions and nicely sits in a tray inside the top of the unit.

Customer review from the Amazon Vine™ Program (What's this?)
Among all the air cleaners I have seen, this one is truly the best. On the very first day that I had it delivered, I decided to try it out and brought a cigarette into the living-room where I placed the WINIX WAC9500 AIR CLEANER. We never allow anybody to smoke in our house but I decided to use cigarette smoke to test this product just for once. The moment this air cleaner perceived the smoke in the room, its air quality indicators started flashing orange and then red and the air cleaner went to work on eliminating the nasty odor of cigarette smoke.
Five minutes later, I asked my husband (who was unaware of the experiment I was conducting) to come downstairs. "Do you notice anything?" I asked. "Yes, the air feels unusually fresh," he responded. The WINIX air cleaner left no trace of the cigarette smoke in the air. If you have smokers in the family or if people who smoke visit you on a regular basis, this product is a must have. It purifies the air and makes it feel almost dewy in its cleanliness. The product description says that it is a great air cleaner to place in your bedroom. I'm not sure that this would be a good idea unless your bedroom is really huge and you will be able to place the air cleaner far away from the bed. WINIX WAC9500 AIR CLEANER is a lot quieter than any other air cleaner that I have seen. However, it isn't completely noiseless. It does produce a certain amount of background noise as it lets the air out. For people who need complete silence to be able to sleep, this will not be an object they will enjoy having in their bedrooms. At this point, I have used WINIX WAC9500 AIR CLEANER in different areas of our house and for different purposes. To give an example, there is some sort of a moldy spot upstairs which creates an unpleasant, stuffy smell. Until we can get people in to take care of it, I placed the air cleaner in the vicinity of the moldy spot and now this is the nicest smelling area in my house. I have also used it in the kitchen, in the study, and in the living-room. The WINIX WAC9500 AIR CLEANER is light enough to be carried downstairs and upstairs easily by a reasonably healthy person. It also looks a lot more pleasing aesthetically than most other air cleaners that often look like their only purpose is to clash with the decor. I have been using WINIX WAC9500 AIR CLEANER for over a month now and haven't been able to find anything I dislike about it.
