[Rewarded Review] Works well

With a new baby in the house, we needed an air purifier to help keep dust and pet dander down for not only the baby’s health, but ours as well. Bosch has been a respected name based on previous research and products purchased so we decided to go with this model. Based on its size, (it’s relatively compact in my opinion) I did not expect it to be able to move as much air as it does when on its highest setting. The room almost feels cooler like having a ceiling fan on. It’s loud on its highest setting, it is a fan after all, but it’s not so loud where it’s annoying. On its lowest setting, you can barely hear it. As for overall purifying, it’s worked really well. The air feels and breathes less “stuffy” and I’ve noticed a reduction in the amount of dust and pet dander residue on surfaces. I’ve been able to breathe easier and I’m sneezing much less on days it’s running. Also did not expect the activated carbon in the filter to reduce odors as much as it does. Typically, cooking odors will permeate the air and surfaces for days afterward, but I’ve noticed a significant reduction in less than an hour of running on high. Most smells are gone within a few hours. Only downside is I couldn’t get the app to work and no carrying handles makes it kind of awkward to move, but it is super light so not a huge deal. Overall, really happy with it so far.

[Rewarded Review] A very nice air purifier, but ...

The Bosch Air 4000 whole house air purifier really is a nice piece of equipment. I've always liked Bosch tools and appliances. This air purifier is huge, and apparently there's another one above this that is even bigger. Considering its size, this thing really lightweight. If it weren't so awkward to carry I could easily swing it up onto my shoulder to walk with it without any grunting or groaning. The entire unit is really broken up into two sections with the top being the motor, fan, and display and the bottom half being the filter and canister. I really like how quiet it is. Don't get me wrong, when it's on high it's pretty loud but it's about the equivalent of an oscillating fan. On the low setting you can't even hear that it's on. Another great feature is the sleep feature. If you hit the sleep button to go to bed the machine stays on but all of the lights on it go out and the speed is adjusted to low. My favorite feature is the glow ring around the top. When the particulate amount in the air is good it glows blue, when it's ok it glows purple, when it's not good it glows orange, and when it's bad it glows red. On the display on top you can see just how good or bad the air is according to it's very sensitive sensors. I would definitely buy more of these because I'm already breathing better, or at least the air feels more fresh, and I'm getting better sleep.

[Rewarded Review] Get rid of pollen with this Air Purifier. Breath fresh clean air again!

Love this quiet whole house air purifier. So quiet. 4 speeds and smart. HEPA filter. Easy to operate with the AUTO mode. Removes pollen which we have a problem with here in Florida. Dander from our pets is a problem as well. Energy Star efficient. The light ring is fun as it lets you know the level of air quality. 3 in 1 HEPA air filter is excellent. Just plug it in and it does the job. Adjusts automatically to your home's needs.

[Rewarded Review] Wonderful for allergies

I’ve been wanted to try one of those home air purifiers that are constantly advertised on social media, but just couldn’t justify spending so much. Then I found this amazing Bosch whole home purifier. Amazing quality at an even better price point. I love that you can set the fan to constantly run or to kick on when pollutants are detected, which is the setting I prefer. The filter seems to be a great quality and offers three stages of purification while the screen shows the levels that are currently detected. The colored lights change according to pollutants detected as well. So far so good! My allergies have already decreased as well. Make sure you get one that’s big enough for your room size to ensure proper function.

[Rewarded Review] Clean air for all and less stress

Breathe easy, I’ve had this running nonstop in our large room with excellent results! First off dust, I have direct sunlight and normally see dust flying freely in the sun beams no more. Second, smell on the night of the first use I tested this to the max, I happen to run the dishwasher and a plastic item ended up melting causing quite the smell it instantly picked up the extremely bad air quality red level, and was hard at work cleaning and within 3hrs the room was plastic smell free and the light returned to normal. This will be a game changer during party times and we need to rid the cooking smell prior to party time. With how tight we have our homes it’s easy for contaminants to get trapped inside with us. The results justify the higher filter price

I have had the Bosch 4000 for a month and it is wonderful , the machine is quiet and has done wonder on the dust in the air . If you move items in the room and cause a little dust , it speeds up on its own . It more than meets my expectations , good product .

have not had the Bosch Air400 long enough to write a review

Good for my allergies and cat odor.

This has been very helpful with my fall ragweed allergies. I notice a big difference with a reduction in my symptoms. I purchased one of each of the three sizes for different areas of the house and have been happy with all three. I put this one in our basement den where there is also a kitty litter box nearby. I noticed a reduction in odor from that thing. It is simple to operate and very quiet - like my Bosch dishwasher (which is one reason I went with this brand).
