It uses a two-stage filtration process that traps the debris inside, and then it cycles air out through its powerful bladeless fan, cooling up to 1,000 square feet.
HEPA vs. PECO filters: What’s the difference?
You have likely heard of HEPA high-efficiency particulate air filters. A majority of air purifiers have HEPA-standard filtering. Some vacuums feature HEPA air filtering as well. These mechanical air filters force air through a very fine mesh fabric to trap impurities that get mixed in the air. To qualify as a HEPA filter, it must remove up to 99.97% of particles as little as 0.3 microns from the air. The great thing about HEPA filters is they become more efficient as the air gets dirtier, whereas electrostatically charged air filters require more frequent replacements.
PECO, or photoelectrochemical oxidation technology, on the other hand, is a kind of filter that does not give allergens, bacteria, or viruses any chance to thrive. Instead of catching these toxins, PECO utilizes light to spark a nano-coated filter and achieve a catalytic oxidation reaction. Basically, organic substances are broken down into tiny, harmless molecules. Since PECO filters don’t collect particles, they can clear pollutants about 1,000 times smaller than HEPA filters. PECO filtering purifies and disinfects the air without you having to dispose of anything.
How to choose an air purifier
There are many factors to consider when choosing an air purifier. Apart from the brand, start with the size of the room where you will use the device. You may spot some models with the AHAM Verified seal. That sale means the purifier has been independently tested and passed the quality imposed by the Association of Home Appliance Manufacturers. You can also compare the CADR (clean air delivery rate), which refers to the volume of clean air an air purifier can produce at the highest speed setting in relation to the room’s cubic footage. The higher the CADR, the faster and more efficient the air purifier is.
If you or your family members have allergies or asthma, you can also look for Asthma and Allergy Foundation of America air purifiers with this certification, which is guaranteed to reduce allergens in the air in both carpeted and hard floor rooms. Examples of Asthma and allergy-friendly certified air purifiers include designated Dyson Pure Hot + Cool models, LG PuriCare, 360, and RabbitAir Minus A2 and A3.
Since air purifiers typically run all day, factor in the cost of energy. Look for the Energy Star logo, which guarantees that the air purifier is at least 40% more energy-efficient than typical models. You’ll need to account for what you’ll spend on replacement filters or buy an air purifier with washable filters. Some air purifiers are overly noisy, so check for quiet operation or night mode statements.
There are air purifiers with specialized filters to take on particular pollutants. HEPA filters are common for handling allergens, pet dander, hair, dust mites, and pollen, while units with active carbon filters are recommended for removing odors. There are also models designed for smoke or people with multiple chemical sensitivities.
While most air purifiers promise ease of use, some units up the ante with built-in smart features. Ordinary air purifiers operate in one or two ways. Those with continuous air filtering work pretty much like a room fan; press your desired airflow speed, and it consistently moves air at that rate. Others have modes for automatic air filtering that detect impurities with air quality sensors and self-adjust to remove them from the air. Smart air purifiers allow you to track and control air quality, typically with a smartphone app. Some smart air purifiers work in conjunction with smart home systems and devices, such as those that are compatible with Amazon Alexa.
The best air purifier is simply one that best suits your needs. Supplementary features such as noise, portability, touch programs with LED indicators, timers, remote, or smart functions are secondary to room size and the appropriate filtration system. Air purifiers can improve indoor air quality by eliminating allergens that are floating in the air.
