Air Purifier, BKJ-33

A very well though-out and built product that does not try to be more than what it should be...an effective portable air-cleaner. With our unprecedented wildfires in the west, our noses and lungs can attest that this product does exactly that. For me, the number one feature starts with the filter. Not only does the filter appear to be of very high quality (thick and heavy including the charcoal section), the filter fits super tight in the filter compartment which means none of the bad air can sneak past the filter media. The second most important feature we like is the choice and quality of the fan which not only does a great job of muscling lots of air through the thick filter when needed, it is super quiet in sleep mode. Third, I like air-cleaner designs that blow air up toward the ceiling like the BKJ-33 because this seems to do a much better and faster job of circulating clean air to all parts of our rooms versus units that blow the air sideways. The portability and weight of the BKJ-33 are also very nice. We also have the larger Colzer KJ800 for our large family room/kitchen area which works great and we love. However, it is not really portable and we needed an air-cleaner for the other rooms that we also spend time in. Lastly, we also like the very clean styling, color scheme (white goes with everything) and the logical control panel.

I am writing this review on the updated Colzer BKJ-33 to let you know what a great and quiet unit this is. I own 2 of the these units, but of an older design, as well as a Colzer BKJ-215; and they are all great units. The redesign of the BJK-33 looks great. It is a little more square than my previous units and slightly deeper, but this is to accommodate a thicker filter. Plus with all the COVID-19 issues of late, having a nice thick filter to help with air impurities is great to have. I also like the air quality indicator they’ve added. It’s nice to look at the unit and know the status. As you will see in the video, the unit is quiet, easy to navigate, and the filter is super easy to change out. I get roughly 3 months with my filters but I have 5 dogs. ; ) The units, including this one, are compact and don’t take up a lot of space. I have been working from home lately due to COVID and I have a unit running in the office 24/7. I have no idea it’s there as it is so quiet. These are great units, quiet, compact, and user friendly.

Anyone complaining about sound level must really have a much quieter home than I do. I just keep it on auto and never notice it running at all. So far ive never had the green circle for great air quality; it just stayed blue. Where I notice the difference is dusting. My whole kitchen and living room area is way better when I dust every other week or so. Saving me money on swiffers!! 😂 Anyways; its a quality product. Looks like the lack of available filters issue has been corrected. So im gonna go ahead and give it 5 stars. It far outperforms air filters ive had in the past but I did spend a bit more on this one too. So im glad it performs as it should!

I highly recommend the Colzer True HEPA Air Purifier. We were looking for a good filter with a newborn in our house, so coming to his health and safety. we wanted to ensure that the air they breathe is as clean and pure as possible. Its True HEPA filter captures up to 99.97% of airborne pollutants, including dust, pollen, pet dander, and other allergens as small as 0.3 microns. The activated carbon filter also helps to reduce odors, smoke, and other VOCs, providing cleaner, fresher air. One of the features that I find most useful is the air purifier's automatic shut-off timer, which allows you to set the purifier to run for 2, 4 and 8 hours before turning off. This is helpful if you want to run the purifier overnight or during nap time without having to worry about remembering to turn it off. It also has a "Ultra Quiet" mode, which is perfect for use in a bedroom setting. Additionally, the air purifier has a filter replacement indicator light, which will alert you when it is time to replace the filters. It's advanced filtration, Smart Sensor technology, and quiet operation make it a top pick for families who want to provide the cleanest, safest air for their loved ones.

Very Good Air Filter. I have it located in the living room corner. I especially like how it has an auto-speed fan that speeds up when the sensor notices more dust. I live in Yuma where we get occasional dust blowing from the dunes/ desert. When I open my garage door on a dusty day the sensor kicks in and the filter picks up speed for a couple of minutes. This filter has a smaller foot print and blows air straight up. It is a good alternative to the also good filter made by Whirlpool; Models 450/ and 510, which I also use in other rooms. This Colzer filter is quieter than my Whirlpool air filters which move slightly more air. The downside is the replacement filter costs as of April 2021 $50. I've learned it's not necessary to remove the screen filter from the inside of the plastic cover of the Colzer, so it is easy to vacuum it off. The main hepa filter is easy to replace also. The sensor does need an occasional cleaning per others advice. I've never had an issue with the sensor.
