Why We Like It
Have you shopped for a HEPA air purifier at all? Because it’s amazing how hard it is to find one that:
- cleans the air
- in as wide a space as claimed
- of all the particulates claimed
- which is of high quality
- and is backed by high customer service
So I’m happy to say I found a Grade A HEPA air purifier with a great reputation from a solid company.
Room Size: The COLZER BKJ-33 cleans an 800 sf. room.
What it Cleans: Pet dander, pet hair, dust, dust mites, viruses, bacteria, smoke, allergens (pollen), cooking odors, and PM 2.5. What is PM 2.5? It’s “Particulate Matter 2.5,” the stuff in dirty air that makes the horizon hazy. It’s particularly nasty in smoggy area, making the COLZER the right air cleaner for smog.
Filters: The filter is replaceable and is available here on Amazon. The filter is HEPA (the only kind you want for allergies). COLZER says it should last more than 6 months between replacements.
Air Quality Sensor Light: The BKJ-33 samples the air and displays an score on the control panel. It will show as blue, green or red, which stand for Excellent, Good, and Poor
Fan Speed: The BJK-33 has three fan speeds. The unit senses particles in the air and auto adjusts to the right speed for the current air quality.
Sleep Mode: The BJK-33 is unbelievably quiet on sleep mode at 28 dB, which is just about the same loudness as someone whispering. I’m partial to white noise when I sleep, so I’m looking forward to using this unit in my bedroom. All the light indicators go dark while the unit is in sleep mode.
Timers: In Auto mode, the purifier senses the air and adjusts power according to the air cleaning needs. In Timer Mode, the COLZER can be set to run 1, 2, 4, or 8 hours and then shut off to save energy.
Warranty: 60 Day Money Back or Exchange; 24 Months on the Unit
CADR: 194 CFM
Bacteria and Viruses: I just love COLZER’s answer to a customer’s question about whether the BKJ-33 air purifier killed viruses and bacteria. “Does not have this feature. The principle of the air purifier is to adsorb bacteria and viruses on activated carbon or HEPA filter nets, resulting in water shortage and death, not directly killing bacteria and viruses.”
This is such a scientifically honest answer. Note the word “adsorb.” With “adsorption,” the virus and bacteria stick to the filter. The little buggers eventually die while stuck to the HEPA surface.
The end result is the same, but I appreciate that the seller didn’t say “yes, it kills viruses,” because that is technically incorrect. It allows them to die.
To that end, it is always a good idea not to shake a filter as you dispose of it. Put the used filter in a tough plastic bag, and then tie it off.
