See all 74 customer reviews See all 74 customer reviews (newest first) On high has a constant high pitched sound.No pre filters at all.Picks up strong smells and starts to distribute them throughout Livingroom...Both my children have bad allergies and I notice a big difference when we run it. I bought this product before in a store and loved it. I got this one online and I think I got a defective one because the UV light only works some of the time and the filter does... I bought this product for my grandson. Poor kid is allergic to cats and his mom brought home the cutest black kitty ever. My sister just bought this for my mom and I. We have neighbors down stairs that smoke cigarettes non stop and the smell is terrible and overwhelming. Love it but blue light is to bring if u keep it in ur bedroom to sleep but so far so good I keep it on low and don't hear it good thing I bought two of these, first one within 2 hrs started blinking on the uv light, no idea why no info in the manuel I unplugged it plugged it back in and do far it's been fine the...

This product works quite well!!!. and is super quiet.Wish Amazon sold replacement filter / light. This is the second Therapure I've purchased. Original is still working, wanted a second unit for another room. so far i like it.. haven't had to clean the filter yet though.. See and discover other items: air purifier fan, pet hair room air filtersStrengths & Weaknesses -- Similar to Hoover but not as RefinedWhat's this?Lemmie say, I have a lot of experience with air purifiers. I have respiratory issues, and literally have 3 -- er... now 4 -- different ones going right now; Hoover Air Purifier with TiO2 Technology - WH10600,Oreck AirInstinct HEPA Large Room Air Purifier and the Rabbit Air BioGS which no longer seems to be available on Amazon. I'm not surprised, because the Rabbit Air was the least refined of the lot and most expensive in filter replacements. So now I add Therapure to my Boy in the Plastic Bubble lineup. Ok, its not really like that Travolta movie, it just seems that way with all the HEPA filtration we got going on!

Therapure - The New Kid on the Block ...and it ShowsThis air purifier has promise. But its also shot itself in the foot in a lot of instances. Here's why:Arbitration Agreement - Really?!?The first thing I notice upon opening the box, is a green leaflet with legal jargon on it, telling me if I decide to keep this unit past 30 days, then I've entered into a binding contract assuring that I won't participate in any class action lawsuits or litigation. honeywell 50150 hepa air purifier manualAm I a customer or your future ex-husband? ionic breeze gp air purifier s1830I shouldn't have to agree to a pre-nup just to use your product. alen breathesmart hepa air purifier reviewBig turnoff and silly beyond belief.

Timer FunctionNot sure where this one's coming from. Set a timer to have the air purifier turn on anywhere from 1-24 hours in the future. As if I'm planning on expecting pollutants in the air at a specific time? Life doesn't work that way, and timers on HEPA filters suggest a blatant misunderstanding of how pollutants and allergens work. This filter needs a SENSOR not a timer.No SensorAny air purifier worth its salt has a sensor on it that increases efficiency and flow based on the ever changing environment in which it exists. No Auto FeatureThis purifier has 3 fan settings. Since it has no sensor, there's no way for it to make its own adjustments, so you have to decide up front how polluted your environment is. In one respect, it makes logical sense to put this on High and leave it there, so it continually cleans the air with maximum efficiency. However, there are certainly times when one needs varying degrees of filtration. It's not a question of electricity, but rather how much continual air flow you want in the room.

An auto feature is just essential in my opinion. If not, then just put this thing on High and forget about it. Because running it on lower speeds is the same as buying a less expensive purifier with less capacity. Make no mistake, unless you're in a plastic bubble, there's always something in the air that needs to be filtered. So for me, it's High, Auto, or what's the point?Not Bedroom Friendly... at least not without duct tape. There's far too many glowing lights for this to be usable in a sleep environment. This is literally brighter than a nightlight, and definitely glares in a darkened room. And there's no way to turn any of that glowing annoyance off. It was the same problem with my Rabbit Air, and like that one, all these nifty little lights are utterly useless if you have to cover them up and tape them off, just to go to sleep. You either have to constantly remove that stuff and put it back on at night, or ruin the entire look by permanently leaving it on. And at that point, why bother with any of the lights in the first place?

This one is better suited for a den or living room, or possibly a bedroom, if you don't mind bright lights or use a sleep mask.Now For The Good Parts:> Permanent Filter - Just pop off the back vent and vacuum it clean. Do NOT Wash it! If it does get damaged, or stained over time, replacements are inexpensive.> UV Bulb - Disinfects and cleans the air. This is a proven technique used by hospitals and is highly efficient, and by far, the best feature of this purifier. Replacement bulbs are also inexpensive, so Bonus points on that one.> Sleek Design - Looks chic and cool, and I actually like the illumination, just not for the bedroom.> Nice Controls - Everything is nicely laid out and easy to read on the top of the unit. Just plug it in, and turn it on, and you're good to go. However, it remembers none of your settings. So if you turn it off and back on, or have a power failure, you have to remember to turn the UV light and ionizer separately. Other purifiers remember your settings.> Included Ionizer - Helps clean the air more efficiently, but does cause particles and dust to accumulate near the unit.
