  • Helping with ASTHMA + ALLERGIES! Also one of the better looking air purifiers out there.
Color: Oak Size: Dust, Mold, Pet Odors Style: Filtration
If you are thinking of getting the Alen FLEX air purifier to help with allergies or asthma or pets, read on (because I have all 3): For context, I had been having worsening asthma and allergy attacks over the past few months, to the point where my asthma went from being predominantly exercise or allergy induced to recurring several times a day. After a trip to an asthma and allergy specialist and receiving a full allergy test, I was told that I was allergic to almost everything (every tree, grass and weed, dust mites, cockroaches, cats, dogs, etc. plus other food and miscellaneous allergies). I already knew I was allergic to all of those things but the doctor confirmed that I was on the "severe" end of the scale and I was advised to get rid of our cats and get an air purifier. As most cat owners know, getting rid of a beloved cat would be like throwing your child out on to the street, so the cats had to stay even if it meant using inhalers twice a day, popping allergy medication daily and maybe just banning the cats from the bed and wardrobe. But we knew we would need a GREAT air purifier to help with all the allergens coming from our furry friends and everything else permeating our allergen-laden Northeast American air. You know how some people have "spring allergies"? I have spring, summer and fall allergies thanks to the wide range of trees, grass, and weeds that all decide to pollinate at different times. I had been obsessed with getting a Molekule for a while, and if not, a Dyson. But to be entirely honest, neither was in our current budget due to a recent influx of life expenses. My husband and I agreed that getting a second air purifier from one of those brands might be in the cards when we move into a bigger home in a year, but for now, I should buy the best possible air purifier in the $300 range to cover 700-800 square feet. After days of research and reading hundreds of reviews, I finally settled on this Alan FLEX purifier in Oak. It's a beautiful air purifier, and if you have a home with a more natural aesthetic like we do, the "wood" front helps the machine blend in more with its surroundings instead of sticking out like a sore thumb. We tend to like wood, natural fibers, ceramics, etc. for our decor, and I wanted a purifier that was barely noticeable at a glance because it somewhat camouflaged with its surroundings. Because it has such a minimalist design with clean lines and few obvious vents or mechanical-looking parts, I feel it would blend well with most decor schemes, and it's so great that this model also has numerous colors and wood types to choose from. As for how well it works, I could not confirm its effect on my health immediately but 3 weeks later, I absolutely noticed a reduction in the frequency of my asthma attacks. While I was having several attacks a day, I now have one every 2 to 3 days, and my health in general is improving with each passing week. With cats in the house, things are never going to be 100 percent perfect in that department but this air purifier has made significant improvements. I also wake up a lot less with puffy red eyes or a scratchy throat. For the price point - neither cheap nor extremely expensive, I honestly do feel that Alen FLEX may be the best (if not, one of the best) options on the market, and is a wonderful combination of effectiveness and good design. On the downside? It can be a bit loud when on the highest setting, which may be an issue for those interested in placing it in the bedroom like we do. Not overly loud but it depends on your personal opinion/perception of what constitutes "loud" for such a machine. Personally, I don't really notice the noise anymore - it's almost like white noise in the background. And I think that if it's bothersome at night, you can put it on the low setting, which significantly reduces the noise when you sleep. ... show more

  • Easy to use, looks good, and does a great job
Color: White Size: Dust, Mold, Pet Odors Style: Filtration
I've been using this for over 2 years now (bought Aug 2022), and it works like a dream. It's very quiet, and cleans my air well. It takes many months for the filter to get to the point of needing vacuuming or replacing. I leave the unit on 24/7/365 and have had zero problems with it. If I needed a second one, I'd happily buy this one again. ... show more

  • Expensive, but so worth it
Color: Brushed Stainless Size: Dust, Mold, Pet Odors Style: Filtration
This air purifier is a bit more expensive than others that I looked at, but I recommend it to friends and family all the time. Noise level: On the lowest two settings, this air purifier is essentially silent. The highest setting is definitely loud enough to be heard, but is quiet enough that it is just background noise that you don't notice. For reference, my friend has an air purifier that they bought for about half the price and their lowest setting produces the same amount of noise as my highest setting (while my purifier works much, much better). Air purifying: On top of being virtually silent, this air purifier cleans my air so well. Spring is starting in our area and typically I have terrible allergies, even while in my home. I have not had any symptoms inside my house this year yet. It also helps with odor in my apartment. When I first moved in, it had a slightly musty smell and within about 1 week, the musty apartment was smelling fresh and normal. It also combats cooking smells like bacon, onions, etc. Design: It has a chic design that doesn't scream "air purifier" the minute you see it. It is meant to blend in with your furnishings and because it is so quiet and chic, it's not an eye sore. TL;DR: Great air purifier that is quiet, effective, and aesthetically pleasing. Definitely worth the price. ... show more

  • Excellent air filter
Color: Brushed Stainless Size: Dust, Mold, Pet Odors + Heavy Smoke Style: Filtration
The first thing is this filter is very quite. Even on the third fastest setting, the noise just blends into the background. I am not sure how they accomplished this but it is very quite. The filter works great and the upgraded charcoal filter cartridge removes unwanted smells, such as smoke, very well. Easy to operate, simple to change the filter with no tools, and very slim which allows it to fit up against a wall out of the way. I love the finish options and the front cover is very stylish even though it is plastic you would never know by looking. Best of all it captures dust, bacteria, pet dander, pollen and viruses. Best of all it eliminates smoke odors. I am very happy with this purchase. ... show more

  • Great Product for the Price
Color: White Size: Dust, Mold, Pet Odors Style: Filtration
I received the Flex air purifier a little under two weeks ago, and am very pleased with how it has made such a noticeable difference in the quality of the air in my master bedroom. I have since purchased and received the 75i model and am just as pleased with it. I don't have a lot of experience with air purifiers, but here's what I can tell you. The Flex model is louder than the 75i model, which I can barely (have to try) hear. It is a more basic model without all the bells and whistles of the 75i model. It looks the same, only a little smaller. Both have a sleek, clean, and aerodynamic look about them. They fit against the wall and take up very little floor space as a canister model would take up. I noticed a difference in the air quality in my bedroom within 2 hours of running the Flex air purifier on high setting. I run it 24/7 on the highest fan speed. I am getting used to the loudness of the fan on the Flex. It's not any louder than the HVAC fan when it's running, but it is louder than the 75i model, and it is noticeable for a bedroom. I'm not sure I'd notice it in the kitchen, bathroom, or hallway. It's not keeping me awake, but I wish it was as quiet as the 75i. It doesn't have the bells and whistles the 75i model has - no auto clean mode, no colored lights to tell you the quality of the air, and no ionizer, but is also under half the price of the 75i model and well worth every penny. After nearly 2 weeks of constant 24/7 operation, the Flex model is well worth the investment, and I'm very pleased with it. ... show more
