So, how does the AP300 clean indoor air? It utilizes a 3-in-1 filtration system that captures ultrafine particles. The first line of defense is an activated carbon filter that refreshes the air by trapping odor molecules. Instant Air Purifier AP300 Some devices have additional filters, like carbon or charcoal filters, that trap the petroleum-based gases known as volatile organic compounds (VOCs). Carbon filters also act as natural deodorizers, which makes them suited for the kitchen, too. When installed in Instant Air Purifier, works to remove 99.9% of bacteria and mould from treated air 1

We then conducted a home test separately to compare the design and ease of use of each air purifier in a real world environment. For energy, we hooked up each device to an electricity usage monitor and ran it for a full 24 hours. To figure out the noise output, we used a decibel meter and ran the purifiers at a set distance of three feet away on both the lowest and highest possible fan settings. We also took an ambient room reading to make sure that the fan noise was not being overpowered by the outside world. In fact, according to The White House: ‘Cleaner indoor air improves cognition and productivity, reduces the spread of other airborne diseases, protects against outdoor air pollutants such as smog and wildfire smoke, and decreases the number of environmental triggers for conditions like asthma and allergies.’ So whether you suffer from allergies or not, an air purifier can help to improve conditions at home. How to choose the best air purifier When you activate Eco Mode, the sensor will instruct the motor to turn on and off, depending on how polluted your home’s air is.

Auto-Sleep Mode Performance:With a CADR of 270, 275 and 280 across smoke, dust and pollen, this air purifier is a strong performer which will suit rooms of up to 418 sq ft. It would perhaps suit those who struggle with pollen allergies the most due to its excelled performance in this field. Even though it is the quietest of the bunch at just 48dB on its highest setting, it’s also worth mentioning that it tends to use more energy than other devices at 0.241 kWh in 24 hours, so all that data comes at a cost. The app does improve the overall performance though in terms of better accessibility and additional settings — one feature solely possible through its app is the capability to dim all the lights while keeping the fan at a particular setting. The sensors have a margin of error of +/- 20 micrograms per cubic meter in detecting changes in air quality.

Based on testing of SARS-CoV-2 conducted in lab conditions, using a 13 cubic foot chamber to protect scientists from exposure. Not proven to prevent COVID-19. Performance was measured after 10 air changes through the purifier at minimum fan speed and with plasma ion technology enabled. Actual results may vary depending on operating environment (temperature, humidity, room size and shape, nature and number of airborne particles, etc.), device placement, and product usage (running time, operating mode, etc.) . Best results with continuous use. As a result, the Dyson Pure Cool TP01 didn’t make the cut, and missed featuring in our best air purifiers list. It’s a great-looking fan, but we wouldn’t recommend it as an air purifier based on the CADR results. Sensors monitor air quality and adjust fan speed automatically to work 24 hours a day, 7 days a week 3 Intelligent sensors monitor air quality and adjusts fan speed automatically to work 24 hours a day, 7 days a week(2) You don’t need to suffer from allergies to take advantage of an air purifier though. Air purifiers can improve the air quality at home in general, reducing the level of pollutants you breathe.

Air-purifier noise levels range from nearly silent to steady humming, like an AC unit. Depending on the fan speed you're using and where you're placing your purifier, you may prefer a quieter device. Before settling on a particular air purifier model, it’s important to know how far the device can reach.

I didn’t even have to refer to the manual during testing. The filters just snap into place when they require replacing as well. We tested the Dyson Pure Cool TP01 air purifier to the same standard as those above, and unfortunately it did not deliver a comparable standard of performance. Our lab tests revealed a CADR of 71.7 for smoke, 68.5 for dust and 72.8 for pollen. These were the lowest CADR scores of all of the air purifiers we tested, with only IKEA’s FÖRNUFTIG air purifier coming close.
