What to Consider When Buying an Air Purifier

Air purifiers have taken off in popularity this year, resulting in more brands and models to choose from than ever before. The endless choices and countless features currently on the market can be overwhelming, so we’ve put together a list of important aspects to consider in your air purifier search.



Multiple stage filtration should play a large role in your purchase. Filtration stages vary with every unit and the one best suited for you depends largely on your environment. Different types of filtration address different types of indoor aspects that affect your air quality. Consider the issues that you want to address so you can find an air purifier that matches your needs.

When looking for the perfect air purifier for you and your family, an effective starting point is looking for a unit that has a pre-filter. A pre-filter is the first line of defence against the largest airborne particles found in your home and prolongs the lifespan of the unit’s other filters. Winix air purifiers boast a pre-filter that is both fine-mesh and washable, ensuring maximum long-lasting performance. This evenly perforated fine mesh filter seamlessly fits and connects to the unit’s other filters, resulting in advanced particle absorption. Carbon filters are important as they reduce VOCs and household odours. There are various types of carbon filters on the market today and their performance will vary depending on the environment they are in. These filters are also designed to catch airborne particles found indoors, which helps prolong the True HEPA Filter life. A True HEPA filter is essential as it must satisfy certain levels of efficiency. Winix True HEPA filters are rated to capture 99.97% of airborne allergens including pollen, mould spores, dust, pet dander, microbes, and smoke (particles as small as 0.3 microns in size).

Auto Mode and Smart Sensors

A unit that automatically adjusts according to your indoor air quality allows you to turn your unit on and essentially forget about it. Every Winix air purifier carries this convenient feature, referred to as Auto Mode. Auto Mode and Smart sensors work together within the air purifier by detecting and monitoring your current air quality. These built-in smart sensors read your current air quality and adjust fan speeds accordingly in real-time. An added benefit is the light automated sleep mode, as it turns on when the room is darkened and instantly provides you with continued air cleaning at an undisturbed level of noise. The information gathered by the unit’s smart sensor is visually displayed by the LED Air Quality Indicator on the unit’s panel, representing your air quality as either good, fair, or poor.

Filter Replacement

In order to receive the most effective results from your air purifier, you will have to replace your filters. Depending on the air quality in your home, filters may need to be replaced more often. The average lifespan of a filter is 3 months to 1 year. Winix includes a minimum of 1 year worth of filters inside of every air purifier, leaving you to enjoy clean air all year long.


With so many air purifiers to choose from, it’s important to know that the product you’re purchasing will do what it says. An AHAM certification means the unit has been tested and proved for its ability to remove smoke, dust, and pollen from the environment. An Energy Star certification means the air purifier has met the strict energy-efficiency guidelines set by the U.S. Environmental Protection Agency. Air purifiers with this symbol use less energy, resulting in reduced operating costs and protecting the environment.

Noise Level

The operating noise is a factor you should consider in your search. This noise will increase or decrease depending on the fan setting but there is a decibel (dB) range you should stay within to avoid a distracting unit. Winix air purifiers go as low as 25dB, meaning the unit is no louder than a human whisper.

Now that you’re able to narrow down your options, searching for the perfect air purifier should be a less daunting task. Keeping these tips in mind will ensure you get the most out of your purchase, but more importantly, that you provide yourself and your family with the cleanest air.
