Kenmore Electrostatic Air Cleaner —
I have cats, dogs and birds. This unit has made a big difference in my air quality. I bought several air purifiers including the Kenmore Envriosense. It has outlasted all of my other purifiers and I keep it going 24 hours. I don't have to buy replacement filters a +++. (I find if I have to buy replacement filters, I usually forget to buy them and wind up putting the unit in storage and forgetting about it.) Yes it is kind of big and not very pretty but worth it. My metal cell needs to be cleaned approximtely every 6 weeks. The prefilter approx every 3 weeks. I soak it in a slop sink in dawn dishwashing liguid and wipe down. Be careful the metal edges can cut your fingers.
