I am deathly allergic to the blooms of the Sweet Acacia tree, which happens to be a popular choice of landscapers in Phoenix. I can physical sense the presence of Sweet Acacia from a good 20 meters, and the mere thought gives me a Pavlovian response. The blooms are my kryptonite.
My allergies hit so hard this year that I decided to invest in a quality air purification unit. Iâ€™ve had several inexpensive HEPA-type units over the years, but none that have made a significant difference to my nose. I am very attracted to the filterless design of the Sharper Image Ionic Breeze, but various accounts show that not enough air moves through it, and itâ€™s measured effectiveness at removing allergens is comparatively small. The nicest, hospital-quality units still use filters, so youâ€™re likely to have to live with paying for filter replacements if you want a nicer air cleaner.
I purchased the Friedrich C-90B (click for picture). Itâ€™s a combination of a powerful fan, reusable pre-filter, replaceable activated carbon filter, and a large washable ionizing section. While not cheap (mine was $425 USD here, though the price has since increased), it moves a significant amount of air for a household model, does both electrostatic precipitation and conventional filtering, and produces relatively little ozone. Itâ€™s also large, hideously ugly and must be placed unobstructed on both ends for optimal air flow, but Iâ€™m more than willing to pay that price to be able to breath again. Now why the heck didn’t I buy a decent model years ago? If you have bad allergies, seriously consider ordering one. I’ve found it well worth it.
