Buying Guide: What I Look For in a Purifier
Understanding Filter Grades and Costs
When I evaluate these machines, I look past the shiny plastic. The true value is in the filter. I recommend always checking if a machine uses “HEPA-type” or “True HEPA.”
* True HEPA (H11/H12): Captures 99.97% of particles at 0.3 microns.
* H13 HEPA: Medical grade, capturing even smaller particles down to 0.1 microns.
* Annual Costs: I always calculate the cost of replacement filters. Some “cheap” purifiers require $50 filters every 3 months, making them more expensive than a premium unit over two years.
Matching Capacity to Your Space
I see many people buy a small purifier for a huge room. This is a waste of money because the motor will burn out trying to keep up.
* Check the CADR: This stands for Clean Air Delivery Rate.
* Oversize if possible: I prefer buying a unit rated for 500 sq. ft. even if my room is only 300 sq. ft. This allows you to run the fan on a lower, quieter setting while still getting excellent air exchange.
Common Questions About what is the best air purifier on the market
What Is the Best Air Purifier on the Market for Pet Owners?
In my experience, the best choice for pet owners is a unit with a high-quality, washable pre-filter and a large activated carbon stage. The Coway Airmega is excellent for this because its pre-filter catches hair before it clogs the expensive HEPA filter, and the carbon stage neutralizes pet odors effectively.
How often should I really change my HEPA filter?
Most manufacturers suggest 6 to 12 months, but I recommend checking your filter monthly. If you live in a high-pollen area or have multiple pets, you may need to change it every 4-6 months to maintain optimal airflow and motor health.
Do air purifiers help with kitchen odors and smoke?
Yes, but you need a unit with a thick Activated Carbon filter. Standard HEPA filters are great for dust but do nothing for smells. Units like the Air Health Skye, which features a PRO-Cell catalyst, are specifically designed to break down VOCs and kitchen odors.
Is it safe to leave an air purifier on 24/7?
I actually recommend leaving them on 24/7. Modern units like the Coway or Medify are designed for continuous operation. Running them constantly ensures that the air is always being filtered, preventing the “re-settling” of dust on your furniture.
What is the difference between HEPA and an Ionizer?
HEPA is a physical filter that traps particles. An ionizer sends out a charge to make particles stick to surfaces or each other so they fall out of the air. I always suggest prioritizing HEPA; ionizers are a nice “extra” but should not be the primary cleaning method.
