We have previously tested and reviewed the <a href=\"https:\/\/housefresh.com\/winix-5300-2-review\/\">Winix 5300-2<\/a> and<a href=\"https:\/\/housefresh.com\/winix-5500-2-review\/\"> 5500-2<\/a> with good results, so we know Winix knows how to produce air purifiers with excellent performance at affordable prices.<\/p>\n\n\n\n<p>The Winix A230 comes in all black, and the A231 \u2014 the device we are reviewing \u2014 is white and grey. Besides the color, the Winix A230 and A231 have all the same features and functions. This same device is known as the Winix Zero Compact in Europe.<\/p>\n\n\n\n<p>The Winix A231 is aimed at those with smaller spaces of up to 230 square feet and is a much smaller device than the popular Winix 5500-2.<\/p>\n\n\n\n<p>All Winix devices are sent for independent CADR testing as part of <a href=\"https:\/\/ahamverifide.org\/wp-content\/uploads\/2020\/06\/Air-Cleaner-Performance-FAQs.pdf\" rel=\"nofollow noopener\" target=\"_blank\">AHAM\/ANSI AC-1-2002<\/a>, to see how well the device can remove dust, smoke and pollen. After years of testing air purifiers, I recommend you always choose a device with an AHAM CADR lab result, as this will help you get an adequately powered air purifier to keep your room clean.<\/p>\n\n\n\n<p>All Winix devices use PlasmaWave, a bi-polar ionization technology that can improve particle removal performance beyond HEPA filtration alone. One big thing I like about Winix is that their Plasmawave technology is optional and easily switched off. I wish more air purifiers with an ionizer would offer this.<\/p>\n\n\n\n<p>As with all the reviews we perform here at HouseFresh, we bought the Winix A230 with our own money and have no relationship with Winix. We aim to share the results of our hands-on testing, including a performance test, sound levels, long-term costs and energy usage.<\/p>\n\n\n\n<p>When writing this review, the Winix A231 was $81.22, and the all-black A230 was $78.99 \u2014 this is even cheaper than the popular <a href=\"https:\/\/housefresh.com\/levoit-core-300-review\/\">Levoit Core 300<\/a>, and the Winix device has a better Clean Air Delivery Rate (CADR).&nbsp;<\/p>\n\n\n\n<p>I am excited to see if Winix can offer their usual high cleaning performance in an air purifier that can be found regularly for less than $99.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"the-lowdown-on-the-winix-a231-1h2\"><strong>The lowdown on the Winix A23<\/strong>1<\/h2>\n\n\n<div class=\"gb-container

This is an issue that my wife uncovered: sometimes, when cleaning the floors, she will pick up the Core 300, and the filter falls out because the base of the device was unlocked. The Core 300\u2019s base can easily unlock when moving the air purifier around the floor. With the Winix A231, the base stays on unless you intentionally twist it with your hands, so it is a much better design.<\/p>\n\n\n<div class=\"gb-container gb-container-891d0f15\">\n\n<div

speeds.<\/p>\n\n\n\n<p>Air cleaning performance is essential, but if you don\u2019t want to use the device due to the level of sound, then it won\u2019t matter.<\/p>\n\n\n\n<div class=\"flourish-embed

dBA at the highest fan speed, similar to other Winix devices we reviewed. 57.9 dBA is not quiet enough to use during sleep or work, but it wasn\u2019t excessively high compared to other air purifiers we tested.<\/p>\n\n\n\n<p>At the second fan speed, noise levels peaked at 48.3 dBA. And at the lowest speed, sound levels dropped to 35.2 dBA. This is very quiet, but we wouldn&#8217;t recommend using such a small device at its lowest speed as it just wouldn\u2019t be able to clean enough air, even in a tiny space.<\/p>\n\n\n\n<p>We re-tested the particle removal speed of the A231 at this sub-45 dB speed and it reached PM1 zero in <strong>86 minutes<\/strong> \u2015 a whole 46 minutes slower than when running at its top speed:<\/p>\n\n\n\n<div class=\"flourish-embed flourish-chart\" data-src=\"visualisation\/20776951\"><script src=\"https:\/\/public.flourish.studio\/resources\/embed.js\"><\/script><noscript><img decoding=\"async\" src=\"https:\/\/public.flourish.studio\/visualisation\/20776951\/thumbnail\" width=\"100%\" alt=\"chart visualization\" \/><\/noscript><\/div>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"gb-headline gb-headline-eabe930c gb-headline-text\"><\/div>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"the-cost-to-run-a-winix-a231-zero-compact-119-54-per-year-1h2\">The cost to run a Winix A231\/Zero Compact: $119.54 per year<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"low-energy-draw-and-affordable-filters-keep-annual-costs-feasible-1h3\">Low energy draw and affordable filters keep annual costs feasible.&nbsp;<\/h3>\n\n\n\n<h3 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"1-electricity-costs-69-55-per-year-1h3\"><strong>1. Electricity costs = $69.55 per year<\/strong><\/h3>\n\n\n\n<p>It\u2019s advisable to keep your air purifier running constantly to improve the number of air changes in your room. This means you must be aware of the energy costs because they can add up when running inefficient devices.&nbsp;<\/p>\n\n\n\n<p>Assuming that Winix A231 was on 24\/7 every day of the year at its highest speed, it would add $69.55 to your electricity bill. This level of electricity usage aligns with other small air purifiers and is fair, considering how well it can clean the air.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"2-filter-costs-49-99-per-year-1h3\"><strong>2. Filter costs = $49.99 per year<\/strong><\/h3>\n\n\n\n<p>Winix states that you should change the filter every 12 months for the A231, but this will depend on how you use it and how bad the air is. Thankfully, it also includes an alert to tell you when to change the filter at the top of the device.&nbsp;<\/p>\n\n\n\n<p>Genuine filters are $20 cheaper than those from Levoit for similar-sized devices, so these filters are some of the best value on the market.&nbsp;<\/p>\n\n\n\n<p>If you want to keep costs even lower, you can also go for generic filters that bring the yearly filter costs down to just over $15 if you buy a 2-pack.<\/p>\n\n\n\n<div class=\"aawp\">\n\n            \n            \n<div class=\"aawp-product aawp-product--horizontal aawp-product--ribbon aawp-product--sale\"  data-aawp-product-asin=\"B08NSQ91LM\" data-aawp-product-id=\"15211\" data-aawp-tracking-id=\"airpurifierreviewsite-20\" data-aawp-product-title=\"Winix Genuine 1712-0110-00 Replacement Filter O for A230 and A231\" data-aawp-click-tracking=\"asin\" data-aawp-local-click-tracking=\"1\">\n\n    <span class=\"aawp-product__ribbon aawp-product__ribbon--sale\">Sale<\/span>\n    <div class=\"aawp-product__thumb\">\n        <a class=\"aawp-product__image-link\" href=\"https:\/\/www.amazon.com\/dp\/B08NSQ91LM?tag=airpurifierreviewsite-20&#038;linkCode=ogi&#038;th=1&#038;psc=1\" title=\"Winix Genuine Replacement Filter for A230 and A231\" rel=\"nofollow noopener sponsored\" target=\"_blank\">\n            <img decoding=\"async\" class=\"aawp-product__image\" src=\"https:\/\/housefresh.com\/wp-content\/plugins\/aawp\/public\/image.php?url=YUhSMGNITTZMeTl0TG0xbFpHbGhMV0Z0WVhwdmJpNWpiMjB2YVcxaFoyVnpMMGt2TXpGNFduTjRLemxMUWt3dWFuQm58MTc1NTczNTQ5MA=\" alt=\"Winix Genuine Replacement Filter for A230 and A231\"  \/>\n        <\/a>\n\n            <\/div>\n\n    <div class=\"aawp-product__content\">\n        <a class=\"aawp-product__title\" href=\"https:\/\/www.amazon.com\/dp\/B08NSQ91LM?tag=airpurifierreviewsite-20&#038;linkCode=ogi&#038;th=1&#038;psc=1\" title=\"Winix Genuine Replacement Filter for A230 and A231\" rel=\"nofollow noopener sponsored\" target=\"_blank\">\n            Winix Genuine Replacement Filter for A230 and A231        <\/a>\n        <div class=\"aawp-product__description\">\n            <ul><li>Compatible with Winix air cleaner models A230 and A231<\/li><li>Genuine up to 12 months of filtration!

The Winix A230\/A231 is a great unit for those cases \u2014 for example, for a small bedroom or the top of a desk in a small home office.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1152\" src=\"https:\/\/housefresh.com\/wp-content\/uploads\/2024\/01\/Winix-A231_Editorial.jpg\" alt=\"\" class=\"wp-image-21141\" srcset=\"https:\/\/housefresh.com\/wp-content\/uploads\/2024\/01\/Winix-A231_Editorial.jpg 2048w, https:\/\/housefresh.com\/wp-content\/uploads\/2024\/01\/Winix-A231_Editorial-300x169.jpg 300w, https:\/\/housefresh.com\/wp-content\/uploads\/2024\/01\/Winix-A231_Editorial-1024x576.jpg 1024w, https:\/\/housefresh.com\/wp-content\/uploads\/2024\/01\/Winix-A231_Editorial-768x432.jpg 768w, https:\/\/housefresh.com\/wp-content\/uploads\/2024\/01\/Winix-A231_Editorial-1536x864.jpg 1536w\" sizes=\"auto, (max-width: 2048px) 100vw, 2048px\" \/><\/figure><\/div>\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"gb-container gb-container-3b408f40\">\n<div class=\"gb-container gb-container-7565ae7e\">\n\n<a class=\"gb-button gb-button-337df505 gb-button-31916d68\" href=\"https:\/\/geni.us\/a230HF\" target=\"_blank\" rel=\"nofollow noopener noreferrer sponsored\"><span class=\"gb-icon\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"32\" height=\"32\" viewBox=\"0 0 1024 1024\"><path fill=\"currentColor\" d=\"M485 467.5c-11.6 4.9-20.9 12.2-27.8 22c-6.9 9.8-10.4 21.6-10.4 35.5c0 17.8 7.5 31.5 22.4 41.2c14.1 9.1 28.9 11.4 44.4 6.8c17.9-5.2 30-17.9 36.4-38.1c3-9.3 4.5-19.7 4.5-31.3v-50.2c-12.6.4-24.4 1.6-35.5 3.7c-11.1 2.1-22.4 5.6-34 10.4zM512 64C264.6 64 64 264.6 64 512s200.6 448 448 448s448-200.6 448-448S759.4 64 512 64zm35.8 262.7c-7.2-10.9-20.1-16.4-38.7-16.4c-1.3 0-3 .1-5.3.3c-2.2.2-6.6 1.5-12.9 3.7a79.4 79.4 0 0 0-17.9 9.1c-5.5 3.8-11.5 10-18 18.4c-6.4 8.5-11.5 18.4-15.3 29.8l-94-8.4c0-12.4 2.4-24.7 7-36.9c4.7-12.2 11.8-23.9 21.4-35c9.6-11.2 21.1-21 34.5-29.4c13.4-8.5 29.6-15.2 48.4-20.3c18.9-5.1 39.1-7.6 60.9-7.6c21.3 0 40.6 2.6 57.8 7.7c17.2 5.2 31.1 11.5 41.4 19.1a117 117 0 0 1 25.9 25.7c6.9 9.6 11.7 18.5 14.4 26.7c2.7 8.2 4 15.7 4 22.8v182.5c0 6.4 1.4 13 4.3 19.8c2.9 6.8 6.3 12.8 10.2 18c3.9 5.2 7.9 9.9 12 14.3c4.1 4.3 7.6 7.7 10.6 9.9l4.1 3.4l-72.5 69.4c-8.5-7.7-16.9-15.4-25.2-23.4c-8.3-8-14.5-14-18.5-18.1l-6.1-6.2c-2.4-2.3-5-5.7-8-10.2c-8.1 12.2-18.5 22.8-31.1 31.8c-12.7 9-26.3 15.6-40.7 19.7c-14.5 4.1-29.4 6.5-44.7 7.1c-15.3.6-30-1.5-43.9-6.5c-13.9-5-26.5-11.7-37.6-20.3c-11.1-8.6-19.9-20.2-26.5-35c-6.6-14.8-9.9-31.5-9.9-50.4c0-17.4 3-33.3 8.9-47.7c6-14.5 13.6-26.5 23-36.1c9.4-9.6 20.7-18.2 34-25.7s26.4-13.4 39.2-17.7c12.8-4.2 26.6-7.8 41.5-10.7c14.9-2.9 27.6-4.8 38.2-5.7c10.6-.9 21.2-1.6 31.8-2v-39.4c0-13.5-2.3-23.5-6.7-30.1zm180.5 379.6c-2.8 3.3-7.5 7.8-14.1 13.5s-16.8 12.7-30.5 21.1c-13.7 8.4-28.8 16-45 22.9c-16.3 6.9-36.3 12.9-60.1 18c-23.7 5.1-48.2 7.6-73.3 7.6c-25.4 0-50.7-3.2-76.1-9.6c-25.4-6.4-47.6-14.3-66.8-23.7c-19.1-9.4-37.6-20.2-55.1-32.2c-17.6-12.1-31.7-22.9-42.4-32.5c-10.6-9.6-19.6-18.7-26.8-27.1c-1.7-1.9-2.8-3.6-3.2-5.1c-.4-1.5-.3-2.8.3-3.7c.6-.9 1.5-1.6 2.6-2.2a7.42 7.42 0 0 1 7.4.8c40.9 24.2 72.9 41.3 95.9 51.4c82.9 36.4 168 45.7 255.3 27.9c40.5-8.3 82.1-22.2 124.9-41.8c3.2-1.2 6-1.5 8.3-.9c2.3.6 3.5 2.4 3.5 5.4c0 2.8-1.6 6.3-4.8 10.2zm59.9-29c-1.8 11.1-4.9 21.6-9.1 31.8c-7.2 17.1-16.3 30-27.1 38.4c-3.6 2.9-6.4 3.8-8.3 2.8c-1.9-1-1.9-3.5 0-7.4c4.5-9.3 9.2-21.8 14.2-37.7c5-15.8 5.7-26 2.1-30.5c-1.1-1.5-2.7-2.6-5-3.6c-2.2-.9-5.1-1.5-8.6-1.9s-6.7-.6-9.4-.8c-2.8-.2-6.5-.2-11.2 0c-4.7.2-8 .4-10.1.6a874.4 874.4 0 0 1-17.1 1.5c-1.3.2-2.7.4-4.1.5c-1.5.1-2.7.2-3.5.3l-2.7.3c-1 .1-1.7.2-2.2.2h-3.2l-1-.2l-.6-.5l-.5-.9c-1.3-3.3 3.7-7.4 15-12.4s22.3-8.1 32.9-9.3c9.8-1.5 21.3-1.5 34.5-.3s21.3 3.7 24.3 7.4c2.3 3.5 2.5 10.7.7 21.7z\"><\/path><\/svg><\/span><span class=\"gb-button-text\">PRice AT amazon<\/span><\/a>\n\n<\/div>\n\n<div class=\"gb-container gb-container-e765a32e\"><\/div>\n<\/div>\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>When it comes to competitor units, I have to compare the A231\/Zero Compact to the Levoit Core 300 and the Core 300S.
