Other Features

If you live in an area with a high level of humidity, you can be affected by the mold and mildew that can develop due to all the moisture from the air. So, you must opt for an appliance that can also reduce bad odors besides eliminating bacteria. The Alen A350 HEPA air purifier integrates a HEPA technology and an Activated Carbon System to capture pollutants and eliminate bad smells. However, this type of machine can only reduce light odors, so if your main problem is that you live in an area with bad smells, we recommend you a device that can deliver a higher performance. Still, if the odor is not something that you worry about, we highly recommend you this air purifier.This model is an Energy Star Certified product, which means that you will be able to save money on your energy bills, so you won’t have to worry about big additional costs.

Final Thoughts

This is an overall good air purifier that performs well. Unfortunately, the Alen A350 HEPA does not provide as impressive of a performance as other top of the line models do, but it is still worth taking into consideration, especially if you are looking for a unit that will consume as little energy as possible when operating. Also, due to the fact that it features HEPA filtration, it is capable of removing a considerable amount of airborne particles that linger in the indoor air, more precisely up 98 percent of the impurities that it finds. Therefore, if you are looking for an air purifier that it both cheap and that does not consume much, this model is the right choice for you, but do not get your hopes up performance-wise because it is not the best option out there.

    I’m wondering whether this purifier can handle eliminating smoke as well. There are three smokers in my household, and the smell indoors is usually extremely bad.

  • James

    I couldn’t believe my eyes when I saw what a huge area this model can purify the air in, but now that I have bought and tested it myself, I can guarantee that it’s all true!

  • Martin

    We have one of these air purifiers at the office where I work. I’m actually very impressed with it, and I plan on buying one for home use as well.

  • Logan

    I needed an air purifier for the basement, so I bought this one since it says in the review that it can cover big surfaces. Since I use it in here, I am able to sit for hours on end working in the office that I improvised here without starting to sneeze frenetically. Thanks for the review and for opening my eyes about this amazing air purification system!
