BLUEAIR Air Purifiers for Bedroom Small Room Air Purifiers for Home Air Purifiers for Pets Allergies Air Cleaner, HEPASilent Virus Air Purifier for Dust Baby Air Purifier for Nursery Blue Pure 511ENERGY STAR

The Blueair Blue Pure 511 air purifier has been a fantastic addition to my home. It’s compact, sleek, and fits perfectly in a bedroom, nursery, or small living area. The design is modern yet simple, making it easy to blend into any space. Setup was straightforward—plug it in, and it’s ready to go.This purifier’s standout feature is its HEPASilent Technology, which combines electrostatic and mechanical filtration for top-notch performance. It captures dust, allergens, and even pet dander without making a sound. I noticed a difference in air quality within hours—my room feels fresher, and my allergies have significantly improved.Another big plus is how whisper-quiet it is, even on higher settings. It’s perfect for nurseries or bedrooms where noise can be an issue. The energy efficiency is impressive too, so you can leave it running without worrying about your electricity bill. Maintenance is simple, with a quick filter change every few months.If I had to nitpick, I’d say it would be nice to have a built-in air quality sensor, but for the price and performance, this purifier is excellent. Whether you need relief from allergies or just want cleaner air, the Blue Pure 511 is a must-have!

The Blueair system works great in our Family Room to remove dust and pollen. The system is very quite I can't even hear it run. Yes, I would recommend this product. Note: make sure you buy a couple extra filers they last about 6 months each. Very easy to operate.

This air purifier is fantastic!So quiet & effective.New filter on left. 6month old used filter on right. I highly recommend this air purifier.

I like the effectiveness of this air purifier so as far as performance goes, I think it should have five stars. Since there’s no way of testing air quality and we just have to go on faith, I’m guessing that it’s a good quality machine. However, clearly it was designed with aesthetics in mind and not practicality. It’s difficult to turn on an off or to know how to turn it higher or lower. You do this with a series of taps on the top ring. It’s very Star Trek in a very unnecessary way. I love Star Trek. I love everything about Star Trek. I don’t think even they would’ve kept this on the enterprise because it’s too annoying to use , however, having said that I just turned mine on low and keep it on all the time. I have noticed that environmental allergies bother me much less this year. If you are into the super modern look and have the gray walls that all designers think everyone should have now, you might love this look and usage facility might not bother you. I don’t think an older person would be able to use this easily. The only thing that lets you know if it’s on or off is a light that shines for a moment when you tap it. There is delay in the action so you don’t know if you’ve actually turned it up higher or turned it off for a few seconds, so if you’re impatient like me and tap it again, you’ll probably accidentally turn it off and have to start all over again . Again, weird design, leaving you confused. Is very silent and that’s a big plus. It probably deserves one more star, but I’m too annoyed with the lack of the on and off clarity to increase my stars. Here’s an idea, how about somebody make a vintage looking air purifier with simple on off switches, make it look like a vintage radio. I bet that would be a big seller, the nice old-fashioned knobs. On and off.I have no idea how I’m going to change the filter when it’s time to change it, the whole thing is a mystery as to how it’s assembled, and I wish they would just include a few extra filters with the purchase so then you weren’t trying to figure out what kind of machine you have and which kind of filters to buy six months later. I’d be willing to pay extra to have the extra filters delivered with the purchase. If I sound annoyed it’s because I am. But I’m sure the machine is good quality.Updated review 9/11/24: The machine is actually silent on low. It’s been on all day and I didn’t even know it. You literally cannot hear it at all on its lowest setting. It also did a great job getting rid of a smell that was from something burned in my kitchen. So it is a very effective machine. I also now am wondering if the thing that I found fault with is actually a benefit to older people with arthritis if they cannot turn a knob, then just tapping the top might be very helpful to them. In fact, anyone with mobility issues could put this beside their bed and just tap it at night in the dark and it would be easy to use for them. Because it is silent, it will not work for you as a white noise machine. I’m now going to add a star. Xo

I have a relatively small office/den and my dog spends quite a bit of time in here. We had bought one of the larger blue air purifiers and found it worked extremely well. I bought the basic 511 model, which is the right size for my office. While this one doesn't have Wi-Fi and app control, it's easy to Control with a single button. On its lowest setting, I can't even hear it. After a couple of days, I've noticed an improvement with air quality, especially the first time I walk into my office. I think it helps that I put it right next to my dog. 😉
