Okaysou AirMax8L Air Purifier Review (Ad)

I happened to be shopping for a new air purifier for our family due to environmental allergies, asthma, and poor air quality when Okaysou contacted me to see if I would be interested in reviewing their Okaysou AirMax8L air purifier. The timing was perfect. Long story short, even though my husband and I are very picky about air purifiers, we love the Okaysou AirMax8L air purifier! Let me tell you why.

Disclosure/disclaimer: Okaysou sent their AirMax8L Air Purifier free of charge for me to review. I only agree to review products which might help my family and I always share my honest opinions to help you and your family. This post may contain affiliate links. This post is for informational purposes only, please consult your medical care team if you have any asthma or related questions.

The last two years have been very stressful due to the California wildfires. The smoke and poor air quality made it very difficult to breathe, sometimes I was at risk of an asthma flare up and sometimes I was so sick. Even though we kept our windows and doors closed, the particulates still seeps through windows and doors, especially whenever we come in or out of the house. We ran the house fan all day for extra filtration and changed our very dirty HEPA filter frequently. We purchased an air purifier for our bedroom due to all the extra wildfire related smoke and pollution which helped.

We also have had a great air purifier in our sons’ bedroom for 10+ years to help with their environmental allergies. That model was discontinued after a few years and the company recently discontinued making filters, so we needed a replacement air purifier for the kids’ room. In the meantime, we moved our air purifier to their bedroom but we couldn’t reorder our air purifier due to new California restrictions about air purifiers with ionizers.

If you didn’t know, ionic air purifiers create particles which become harmful ozone gas. Air purifiers are meant to improve our health, but ozone generators are a health hazard and, according to the EPA, may cause lung damage which people with asthma or other respiratory issues may want to avoid or check with their medical care team. The air purifier that we moved into my sons’ room has an ionizer but it has an on/off switch which we leave off all the time but there’s still a small risk of accidentally turning it on.

Update 3/27/2020: I’m adding a link from AAAAI’s latest research news about how lung function can drop after a few hours of exposure to small amounts of ozone. “This data further illustrates how low level ozone has an impact not only on those with health conditions such as asthma, but also those who are in good health, even when they’re not physically active. “We urge everyone to do what they can to limit exposure to ozone and other harmful pollution,” said Dr. Hernandez.”

What do we look for in an air purifier?

We need to shop again for a new air purifier and be better prepared for wildfire season with one air purifier in each of the frequently used areas of the home. And we consider the needs of our parents’ in their homes and our son in his college dorm (apartment next year). A bunch of air purifiers is a big investment and we want to be sure we buy what meets our needs at a reasonable price point. Some of the specifications that my husband and I consider when searching for an air purifier include the following:

Health Considerations:

  • What can an air purifier filter? A true HEPA filter can filter out very small particles without creating ions, which become ozone, an irritant for people with asthma. Does it have carbon to filter out odors? Does it have an antimicrobial filter to bacteria, viruses, and mold?
  • Is the air purifier an ionic purifier that generates byproducts which become ozone? If yes, consider whether the default mode is on or off when the air purifier is powered on (for example after a power outage).

Air Purifier Features:

  • What’s the CADR (clean air delivery rating) number, which refers to the number air changes per hour? If you multiply a CADR rating by 1.55 then you can estimate the square footage of a room that the device will clean.
  • How quiet is it? How loud can it become? Usually the manufacturer will give a range in decibels. Normal conversation is about 60 decibels, a quiet working environment would be about 50 decibels. A decibel rating between 25-45 would be comfortably quiet.
  • My husband remarked that the specification for energy efficiency might be when the air rate exchange rate is lowest and the noise is quietest. But the CADR number would reflect when the air purifier would be working hardest and using more power and be louder.
  • What’s the energy efficiency?
  • Is the air purifier unobtrusive in size or shape? Is it easy to move around?
  • Does it have a nighttime or sleep mode to dim the lights, which is more optimal for bedrooms?
  • Does the air purifier have an automatic air quality sensor? That’s a great feature to have for better air quality and better energy usage.

Cost Considerations:

  • How long is the warranty period? That usually indicates the manufacturer’s confidence in the product. My husband prefers a minimum of a two year warranty period or longer.
  • What’s the cost of the unit and what’s the cost of the filters? If you know the warranty period, then you can estimate the total cost of the purifier plus supply of filters over a certain number of years.

Hopefully these general considerations for an air purifier will help you find an air purifier that meets your needs. I was amazed when I realized that the Okaysou AirMax8L is nearly perfect and meets our most important criterias.

How did the Okaysou AirMax8L Air Purifier meet our expectations?

The Okaysou AirMax8L air purifier (affiliate link) is easy to set up, hums along quietly, and does its job which is perfect. But it also has a lot of great features that impressed my husband, who tracks each air purifier that he’s looked at on a spreadsheet. We have been using the air purifier for three weeks now, if there are any significant issues or kudos over the next few years, I will update this post.

The most important features for us include the following:

  • The CADR is 210 which can clean a room that is 325 sq. ft., which is more than adequate for any of our rooms.
  • The Okaysou AirMax8L uses two medical grade filters and needs to be replace about every 6 months (may vary with use).
    • The Okaysou AirMax8L Ultra True Filter (affiliate link) has three layers, a pre-filter to catch big things like hair, pollen, pet dander, a HEPA filter for dust and mold, and an anti-microbial layer for viruses, bacteria, and germs.
    • The Okaysou AirMax8L Duo-Filter Carbon Filter (affiliate link) has two filters, an active carbon filter for cooking odors, smoke, wildfire smoke, and formaldehyde and a cold catalyst filter for VOC, hydrogen, and ammonia.
  • It doesn’t have an ionizer that can generate harmful ozone. It is CARB (California Air Resources Board) certified for sale in California.

Additional features that we love:

  • It’s easy and intuitive to use. There are four 5 simple buttons on the Okaysou AirMax8L air purifier that are labeled. 1) to select the speed, 2) child lock, 3) power, 4) sleep mode to dim all the buttons and set at the lowest setting, and 5) timer so you can decide how long you want the air purifier to run.
  • It’s relatively light, weighs less than 14 pounds. The Okaysou AirMax8L air purifier has cut out areas on the side which make it easy to move from room to room as needed.
  • Its dimensions are 12.9 x 7.1 x 19.4 inches and very inobtrusive in size.
  • It’s also quiet enough for a bedroom or study.
  • The Okaysou AirMax8L air purifier has a 5 year warranty.

Caveats:

  • The only feature that I wish the Okaysaou AirMax8L would have is an automatic sensor to increase the filtration when the air quality suddenly declines or to slow down when the air quality improves. It’s a nice feature to have but it’s also not difficult to adjust the settings as needed. Hopefully they will consider adding that feature in their next model.
  • This is a relatively new company, it’s been in business since 2018. If you have space to store extra filters and you like the air purifier, consider buying and keeping an extra set of filters on hand depending on how long you think the air purifier would last.

Would we buy another Okaysou Airmax8L and filters?

Definitely yes! It’s just a matter of how many and when. Now that we have a great air purifier, I’m hopeful that our family will be safer and healthier this year.

For more information, please visit Okaysou.com. This review is specifically for the Okaysou AirMax8L. They have another small table top air purifier that is considered ozone free but just recently CARB certified.

Update: 3/11/2020 Okaysou notified me that their other air purifier was recently CARB certified, that is so awesome. I have not reviewed it yet but will let you know if I have the opportunity and what I think.
