Air purifier NEWS
Consumer Reports tested dozens of portable air purifiers and whole-house air filters that use high-efficiency particulate air (HEPA) or similar filters to clean the air. If you have a forced-air furnace, it may simply need a filter upgrade. The best filters are designed to capture pollen, dust, or smoke particles; regular furnace filters don't do that. If you don't have a forced-air system, check out our top portable room air purifiers. But skip electrostatic air purifiers, which can produce small amounts of ozone, a respiratory irritant, and ozone generators, which emit higher levels of ozone.
Can a HEPA Vacuum Do the Job?
HEPA filters, which provide the highest level of vacuum-cleaner filtration, can benefit someone with asthma. And in our vacuum cleaner tests, models with a HEPA filter have been very effective at reducing emissions. Some models that don't have HEPA filters, however, have performed just as well, and such vacuums typically cost less than HEPA models.
If you're concerned about a vacuum's emissions, buying one with a HEPA (high-efficiency particulate air) fi‰lter is a good choice. But you can find other worthy models in our vacuum cleaner tests that scored well for low emissions.
