Design and Usability

A mirror to A231 but with modern black housing. The compact size Winix A230 Tower HEPA Air Purifier comes in at only 9.5 inches in diameter and 14.6 inches in height. Perfectly suited for tight areas like a tabletop, desktop, bedside, or TV cabinet with limited space. The lightweight makes carrying Winix A230 a bliss for room-to-room cleaning. Continue with the exterior, the 360° air ventilation setup allows airborne contaminants to be drawn in at every angle. Build quality is top-grade even though it is priced under 100. At this price range, you’re still getting an AHAM Verifide performance, CARB approved/ ozone-safe check, and UL recognized with an official 2 years warranty from Winix.

With its small compact form, Winix A230 is very easy to use as it is essentially a plug and play model. You can effortlessly cycle between the 4 fan speeds or enable Auto mode that uses a higher fan speed when the surrounding air quality level drops. Sleep mode only works manually that disables PlasmaWave, turns off indicator lights, and sets the fan speed to the lowest (lower than low). You can also disable PlasmaWave Technology by holding the buttons for more than 3 seconds. The AQ indicator will display Blue when air quality is good, Amber when it is fair, and Red when air quality is poor. Lastly, the filter change indicator illuminates red when it is time to replace the filter. The removable panel can be easily detached to replace the all-in-one filter change.

Airflow, Coverage, And CADR

Prepare to be amazed at Winix A230 air purifier airflow performance. Despite its compact size and low entry price, it can cover an AHAM Verifide of 230 square footage of room space at 5 air changes per hour. Ideal for an asthmatic or hypersensitive person. You can further extend the purifying coverage to 555 square footage but with a reduced 2 air changes per hour or every 30 minutes. Highly suited for medium room sizes like bedroom, small living room, kitchen, and studio apartment. No other small air purifier can match its airflow output.

Filters And Performance

Like most Winix air purifiers, Winix A230 is powered by the proven 4-Stage HEPA PlasmaWave Technology. When airborne pollutants are pulled in at a 360° angle, the fine mesh pre-filter will capture large particles like dust, hair, fiber, and lint. Without the PM10 pollutants passing through, the activated carbon filter neutralizes smoke from cooking, pet odors, food, chemical fumes e.g. cigarettes, VOCs, radon, formaldehyde while prolonging the HEPA filter life. The True HEPA filter capture 99.97% of airborne allergens small as 0.3 microns such as mold, mildew, pollen. PlasmaWave Technology electrically discharges Hydroxyls to neutralize germs, bacteria, and viruses including influenza strain H3N2. It is safe for home use where only hydrogen from the pollutants' molecular structure is destroyed.

Noise And Energy Usage

Winix A230 air purifier runs quietly with under 25 dB at the lowest speed. Leave it in Auto or sleep mode and you can work, relax, sleep seamlessly without having to monitor it. As an Energy Star certified model, the electric cost is only about $0.04 per day, $1.2 a month, or 14 dollars a year with daily 12 hours of operation. Again, leave it in Auto mode for the best energy optimization.

Pricing And Maintainence Cost

A brand new Winix A230 air purifier will cost you between $79.99 to $119.99 dollars depending on seasonal sales or any online discounts. It is worth every penny you paid considering the number of filtration you'll get and the autonomous features with built-in sensors. Likewise, the all-in-one filter replacement set will only cost you around 50 dollars annually, or roughly 0.14 dollars per day. There are some features omitted like light sensor, timer, and reduced airflow performance, but nothing will hinder its outstanding value.
The best place to buy Winix AM230 air purifier is on Amazon as it comes with attractive discounts, bundled deals, free shipping, and 30 days return policy. Winix's official website is doable as well but the higher selling price might turn you off. You can also try your luck with your local brick-and-mortar store but availability is also non-existence.
