Buy the right air cleaner for your room


It is too small to filter the air effectively. It's too big and you're paying for the fan power and filter size you don't need.

Air purifiers like winix air purifier come in a variety of sizes, types and prices. The best option for you depends on the size of your space, the air pollutants you are most concerned about, and how automated your purifier is.

First, buy the right cleaner for your room. It is too small to filter the air effectively. It's too big and you're paying for the fan power and filter size you don't need.

Second, think about your highest air quality concerns. There are two main types of air pollutants, particulate matter and chemicals, and how much a purifier removes these pollutants depends on the filter mechanism used.

Particles: dust, pollen, smoke
These pollutants include allergens such as pollen and pet dander, as well as smoke residues in the air. If dust is an issue in your area, an air purifier can also help mitigate the problem. In general, the higher the CADR rating and fan speed, the better the filter will remove particles.

Some air purifier manufacturers offer special filters for specific pollutants and allergens. Please refer to the air purifier package and manual to determine if a special filter is available to suit your needs.

Removal of chemical pollutants
VOCs are major chemical pollutants. Many of its sources include paints, plastics, cleaning products, hairsprays and glues. Not all VOCs are harmful, but some are health related and HEPA filters or other particulate filters do not remove VOCs. If you are concerned about chemical contaminants, make sure your purifier is equipped with a carbon filter or other mechanism specifically designed to trap or neutralize VOCs.

A multi-stage purifier with a mechanism to remove particles and chemicals is the best overall solution for removing a wide range of potential air pollutants.

Here are some of the filters you need for an air purifier:
HEPA filter
This is the main filter for your typical portable air purifier. A filter that removes invisible particles in the air and is indispensable for regular cleaning. Check the product manual to see how often you replace the original HEPA filter. Most manufacturers recommend replacing this filter at least once every three months.

Prefilter
Some units have a pre-filter that absorbs large particles such as dust. These pre-filters are usually smaller (and cheaper) than the original HEPA filters. Check this filter for dirt and replace it frequently if it is dirty. The HEPA filter is kept for a long time.

Second pre-filter
Some units include a second pre-filter that attempts to trap small particles before hitting the HEPA filter. In some cases, this intermediate filter is designed to target odor molecules.

Performance ranking
CADR (Clean Air Delivery Rate) is a measure of how quickly a purifier can remove three types of pollutants (smoke, dust, pollen) from the air. Look for more than 200 CADRs for contaminants and omit less than 100. CADR is based on square feet, so choose the model that fits the size of the room you need to filter.

Energy Star certified air purifiers are at least 40% more efficient than non-certified devices. Approved models not only reduce greenhouse gas emissions, but also save electricity over time. Energy Star estimates average savings of $ 25 a year, or $ 215 per unit life.
