4 Fan Speed and Air Quality Indicator

Winix A231 Air Purifier Air Quality IndicatorThe Winix A231 air purifier has four different fan speed settings to choose from, so you can find the perfect level of air purification for your needs. Also, it is equipped with an air quality indicator that switches between Blue (good), Amber (fair), and Red (poor), giving you real-time updates about the quality of air in your room.

Auto Mode + Smart Sensor

These features make the Winix A231 air purifier a good choice for people with allergies or asthma or anyone who wants to breathe cleaner air in their home. The auto mode combined with the Winix smart sensor measures and adjusts the fan speed setting based on the amount of pollution in the air. And ensures that you’re always getting the best possible performance from the machine.

Hence, when the pollutants in your home are minimal, the fan speed will be low, but when the contaminants in the air increase, the fan speed immediately increases to cleanse the air faster.

The Winix A231 air purifier is very easy to assemble. The filter and the cover go in the top, and the machine snaps together in a few seconds. Users do not need to follow any complex instructions, and no tools are required.

Its design is also very simple, flexible and portable, and it doesn’t take up much space. Whether you need to use it in your kitchen, bathroom, bedroom or reading table/corner, its lightweight material makes it super easy to move around.

The Winix A231 air purifier is also very easy to use. And it has a filter indicator light that tells you when it’s time to replace the filter.

Winix A231 Air Purification System: Is it Safe and Effective?

Winix A231 Air Purifier PlasmaWave Technology

Winix A231 air purifier features 360-degree air ventilation that pulls pollutants like smoke, dust, pet hair, etc., from all room angles. More importantly, it uses its patented PlasmaWave Technology and 4-stage air purification system to remove airborne allergens, viruses and bacteria.

Stage 1: The first stage of purification is its pre-filter, and it’s designed to capture large particles such as hair, dust, etc.

Stage 2: Next is the activated carbon filter. Its main purpose is to absorb pollutants like pet odors, smoke, fumes from cigarettes, etc.

Stage 3: The HEPA filter then traps 99.97% of airborne allergens, including pet dander up to 0.3 microns.

Stage 4: Finally, Winix patented PlasmaWave Technology helps create Hydroxyls, which neutralizes airborne bacteria and viruses. It’s also California Air Resources Board (CARB) certified, which means it’s an ozone-free air purifier.

Winix A231 Air Purifier Room Coverage: What Should You Expect?

Winix A231 Air Purifier CoverageThis air purifier is AHAM certified for 230 square feet and is ideal for areas like the bedroom, kitchen, study room and other medium-sized spaces. AHMA certification means that it has fulfilled the standard lab requirements and is fit to remove smoke dust in pollen.

Asthmatic patients and sick people will also find it useful, and ideally, they should set it to 5 air changes per hour to get the best effect and coverage.

As for its clean air delivery rate (CADR), I’ll say it’s somehow low and will give slower outputs. It covers Dust/149, Pollen/154 and Smoke 147(cfm), and because of its portable design, you’ll need to exercise patience and allow it to deliver clean air at its pace.

What is Winix A231 Air Purifier Noise Level and Pricing?

When buying an air purifier, especially one you intend to use in your bedroom, it’s always crucial to go with one that has a reasonable noise level. That way, you’re able to sleep comfortably at night and work effectively during the day.

That said, the Winix A231 air purifier has a noise level of 25 decibels when it functions at its lowest speed, which means you can expect to hear some quiet and sleep-friendly whispers.

Also, when you turn on its sleep mode, the light indicator goes off. This is particularly good for people who don’t want this disturbance.

As for the cost of a Winix A231 air purifier, you can buy it on Amazon at $99.99. More so, its filter maintenance cost is priced at around $50 on its official online store, but you could buy it on Amazon at around $30.
