Reviews
"( BAD NEWS )!!! They now only ship it in the box that’s It originally comes in. There is no extra box anymore. They told me that when I called to complain about the condition of the box it came in ! They quit doing that so my box came all messed up .. and I had black powder all inside the box from the carbon in the plastic bag ..Also, I found out that they do not sale the type of filter for smokers anymore. I found that out because I ordered the wrong one by mistake .. and called them and they told me they do not make that filter no more for smoke / Cigarette smokers. Guess I’ll be finding me another type of. Air purifier machine. their filters were too pricey anyway. So just beware if you order one from them"
"Arrived quickly and on time within 3 business days. Delivered exactly to where I asked for the delivery person to leave my delivery. Thanks. Great product. Lasts 6-months to 1-yr depending."
"My previous filter from Alen had an additional part attached by velcro. This filter does not, nor does it have velcro attachments for the additional piece."
"Exactly as described. I love these air purifiers and filters they last for months"
"This filter is NEXT LEVEL! I underestimated how the upgrade would make a difference in my unit. It feels like I bought a brand new device in my room. I def recommend!!"
"I love how quick and easy ordering was. When I ordered the wrong filter, they sent the correct one immediately. Great product and customer support."
Pure filter
"We started out with the pure filter and I have no complaints! It always looks dirty when it’s being changed out which feels like it’s a good sign that it’s doing its job. The air quality feels great as well. May try one of the other filters at some point just to see if I notice a difference but it is a wonderful thing to feel like I don’t have to buy the most expensive thing just to have something that works really well"
"Upgraded delivery and receive it within a few days"
"Provides consistent in home air quality."
Q&A
- Will this filter also fit in Breathsmart Flex unit? I purchased this filter w carbon and put it in my new Flex unit- Seemed to fit just fine-
- Yes. The BreatheSmart 45i and BreatheSmart FLEX share the same filters.
- How often should you change the filter
- The BreatheSmart 45i filters last anywhere from 9 to 12 months.
- I just purchased the Alen BreatheSmart 45i at a big box store. Which filter type comes in the box with the unit?
- If you purchased your 45i air purifier from Lowes, then you would have purchased either the 45i Pure (B4-Pure) or Fresh (B4-Fresh) filter. The filter type is labeled on the side of the filter.
- Why can't I get a subscription to filters?

- how do I use pre filter
- All of our filters come with a Prefilter attached. On the BreatheSmart 45i filters, the prefilter is the black-mesh attachment with Velcro on the front of the filter. The prefilters' job is to catch the larger dust and debris from clogging your main filter. We recommend vacuuming the prefilter regularly, about once a month, to keep your filter and purifier running optimally. However, some customers (especially those with a lot of furry pets) prefer to replace the prefilter instead.
