Helping with ASTHMA + ALLERGIES! Also one of the better looking air purifiers out there.

Helping with ASTHMA + ALLERGIES! Also one of the better looking air purifiers out there.
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.
