This Type of Air Purifier Can Cut Down on Summer Allergies
June 24, 2019
We’ll cut straight to the chase… the best way to reduce allergies in your Florida home is to invest in a whole-home air purifier. A whole-home air purifier can filter allergens and contaminants out of your home’s air.
The way allergens are removed from your home depends on the kind of air purifier you choose.
Three of the most common whole-home air purifiers are:
Ionic (electronic) filters
UV (germicidal) air cleaners
Below, we’ll break down the details of how these purifiers work and the benefits of each.
Allergy-reducing purifier #1: High-MERV filter
A MERV filter is a type of air filter that works as a net, capturing airborne particles as they pass by it and preventing them from circulating throughout your home.
MERV stands for Minimum Efficiency Reporting Value and measures the effectiveness of an air filter. MERV filters are rated 1–16, with 1 being the least effective and 16 being the most effective.
To remove allergens from your home, we would recommend purchasing a MERV filter that is rated 5 or higher. Why?
5+ MERV filters catch smaller particles that lower-rated filters don’t, like:
However, if you want to install the highest quality filter in your home, you will need to get a high-MERV filter (11+). These filters can catch even more contaminants like bacteria and tobacco smoke.
If you want to install a high-MERV filter, you will need a professional’s help. These filters are thick and a professional may need to make adjustments to the air handler and return duct system to fit a high-MERV filter.
Allergy-reducing purifier #2: Ionic filter
Like a MERV filter, an ionic filter is made up of a media filter (to trap larger particles) and an electronically charged metal layer, which traps smaller contaminants.
This electronically charged layer becomes positively charged and attracts contaminants that escape through the media layer. These contaminants then stick to the charged layer like a magnet.
Ionic filters can catch contaminants like:
Another benefit of installing an ionic filter is that they are reusable. Instead of having to remove and replace these filters every few months, you can simply wash them and reuse them, saving you time and money.
Allergy-reducing purifier #3: UV
A UV or germicidal air cleaner is not an air filter, but a lamp that is installed in your AC system, near the evaporator coil.
A UV air cleaner works by using UV light to kill microbial contaminants, like:
Note: UV lamps sterilize contaminants, but they don’t remove them from your home’s air. That means these lamps are best used in conjunction with a high-MERV filter to catch all airborne particles that may induce allergies. If used alone, these lamps won’t remove particles like pet dander or pollen.
