This brings us to the next question: How long does it take an air purifier to clean a room anyway?<\/span><\/span><\/p>\n<h2><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">How Long Does It Take An Air Purifier to Clean A Room?<\/span><\/span><\/h2>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">In short, most air purifiers take <\/span><\/span><strong><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">30 minutes to 2 hours<\/span><\/span><\/strong><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"> to sanitize the air in your room. In just 20 minutes, there should be a noticeable difference in the air quality in your room.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">For you to determine how long it takes for your air dust filter machine to purify the room, you should know your room size and the Clean Air Delivery Rate (CADR) of your air purifier. This is to know the air changes per hour (ACH ) the air purifier can perform. The ACH is the number of times a certain volume of air can be cleaned from the room in an hour.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">For instance, a home air sanitizer machine has a CADR of 400 CFM and you have a 176 square feet room size. This means the air ionizer machine is running at 4 ACH or cleans the air 4 times in an hour (15 minutes per charge) .<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Your weather, humidity and location can also play a role in how fast the commercial air sanitizer machine works. There are more dusts during summer which means it will take longer for the air purifier to clean the air.<\/span><\/span><\/p>\n<h2><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Is It Safe to Leave an Air Purifier On All Day?<\/span><\/span><\/h2>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Yes, it is alright to leave the air purifier on 24\/7 to maintain a clean indoor air environment. The only downside to this is that the electric consumption will be a little higher. However, air purifiers do not use a lot of electricity which means it doesn't put much cost on your bill.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Remember that dust can easily contaminate the air. So if you choose to turn off your dust purifier machine to save a little on electric costs, this would leave your home as dirty as before you turn it on.<\/span><\/span><\/p>\n<h2><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Should I Sleep With an Air Purifier On?<\/span><\/span><\/h2>\n<figure id=\"attachment_1175\" aria-describedby=\"caption-attachment-1175\" style=\"width: 512px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1175 size-full\" title=\"should you sleep with an air purifier still on\" src=\"https:\/\/hisoair.com\/wp-content\/uploads\/2021\/06\/should-you-sleep-with-an-air-purifier-still-on.png\" alt=\"should you sleep with an air purifier still on\" width=\"512\" height=\"300\" \/><figcaption id=\"caption-attachment-1175\" class=\"wp-caption-text\">should you sleep with an air purifier still on<\/figcaption><\/figure>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Yes, you should turn your air cleaner machine on in your bedroom, especially if you suffer from asthma, allergies or other respiratory illnesses.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">This is because each time you turn off your air purifier, air can become immediately polluted in just 15 minutes.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">A study conducted by the <\/span><\/span><a href=\"https:\/\/smartairfilters.com\/en\/blog\/can-you-turn-off-your-purifier-when-you-sleep\/\" target=\"_blank\" rel=\"noopener\"><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">Smart Air Filters<\/span><\/span><\/a><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\"> showed how air can become 50% polluted in just 15 minutes.
