How do Filtrete filters compare with electronic air cleaners?
The efficiency of Filtrete filters approaches that of the top-of-the-line electronic air cleaners. Some tests indicate that in the large particle size range (1.0-10 microns), Filtrete filters are more effective. Price is a factor, too. Top electronic units cost $500 – $800 and require monthly maintenance. Filtrete filters cost a fraction of this price, and generally only need attention every three months.
