What's the best allergy relief air purifier ? Because that depends on the allergy, and the size of the room you are trying to clean, I'll try and customize an answer just for you. In this article I'll be breaking down the technology by allergy, and make some recommendations based on room size.
I'm sure by the end you'll have the best allergy relief air purifier for your needs, and your budget.
1 - Most HEPA replacement filters are overpriced. This can cost you every 6-9 months after your initial purchase. (See the Comparison Chart via the left menu to check HEPA prices)
2 - HEPA filters can vary in size, but most fit the square footage they cover.
3 - Air Purifiers that have "pre-filters" in front of the HEPA can extend the life of the HEPA purifier - saving you money. They're usually washable, and a good idea for trapping hair and dust.
Because of the pet hairs a pre-filter is especially valuable. It is washable and extends the HEPA life by gathering hairs and some of the dander.
1 - Negative Ions - These are healthy molecules that will kill mold out in the room, and on walls. It is not only safe, it can have a beneficial effect on energy levels, sleep, and breathing problems.
2 - Ozone - While ozone is the most effective way to kill mold it also has a downside. Ozone molecules can irritate lung passageways if breathed in high doses.
3 - HEPA - While HEPA will capture mold spores and keep mold from spreading it will not kill mold in the room, on walls, or in the filter itself. Some companies will promote HEPA as good for mold, but it won't do a good job on mold for these reasons.
