Anyone who’s ever lived with a pet knows that, although you love them, they can be terrible for your air quality. Even those who don’t have a furry friend at home can still suffer from subpar air quality. Every spring, pollen fills the air and potentially activates allergies you might not remember from the year before. Even worse, lots of homes are exposed to artificial pollutants every day. Chemicals from automobiles or cleaning products can cluster on the walls and ceiling. In short, there’s likely no end to the contaminants in the air around you.

That’s why it’s important to have a good room air purifier on hand, especially if you have a young child. Room air purifiers can effectively spread the air of contaminants and make it safer for all debris. The best air purifiers can even stop the growth of mold on the walls or prevent allergies from flaring up. The potential uses and health benefits from these helpful machines can’t be understated.

So how does the Okaysou AirMax8L Medical Grade Ultra-Duo Purifier measure up in comparison to other models? That’s what we aim to find out. In this detailed review, we’ll examine every major aspect of this air purifier. We’ll also look at how it manages to scrub the air clean and how well you work for certain people. Let’s begin.

Purification System

The Okaysou AirMax8L Medical Grade Ultra-Duo Purifier is a multiuse air purifier and odor eliminator. This double purpose makes it an excellent choice right off the bat for both homes and office buildings. Let’s examine how it accomplishes these effects in more detail.

For starters, the AirMax8L is equipped with an advanced turbine motor. This motor has 45 vanes (tunnels through which air can filter). Along with a creative design for the internal structure and a very large air inlet area, it does a great job of sucking up lots of pollutants.

The secret is the five-step filtration process that all incoming air must go through before emerging. The first layer is a “pre-filter” which gets lots of the general dirt or debris of larger sizes out of the way. The HEPA filter is next; this is the same kind of advanced filter you’ll find used by the best vacuum cleaners. And antibacterial filter follows immediately after. This filter is treated with antibacterial components that can neutralize bacteria which is stuck on the surface. This is important so that bacteria don’t continue to grow while stuck on the filter. Ultimately, it does a great job of purifying the air in this way.

The fourth layer is a honeycomb activated carbon filter. Why carbon? Carbon is a type of molecule that can very easily bind to other molecules in the air. It has to do with its molecular structure. That’s why you’ll often find carbon filtration systems for car air filters. Here, it does the same excellent job at trapping anything that has not yet been caught by the other filters. Then there’s a fifth and final filter called the cold catalyst filter. This chills the expelled air and arrests any final air pollutants that might be remaining. Pollutants like formaldehyde and ammonia are both capably trapped by this final filter.

That’s a lot of filters! But the end result is very well worth the effort and asking price. In total, the AirMax8L captures 99.97% of all air pollutants. It can even trap pollutants as small as 0.25 µm: that’s getting into molecular-sized territory! Because the turbine motor drags air into the filters with significant force, it also picks up heavier stuff like pet hair. Thus, it’s an excellent filter for getting rid of pollutants that can easily cause allergies. It’s actually one of the best air filters when it comes to capturing pet hair and dander that we’ve seen so far.

Air Cleaning Capacity

Thanks to the powerful motor infiltration layers, it can circulate air up to 1.5 times per hour with an 800 ft.² room. Smaller rooms can be purified many times over. Simply stick this filter in any room you prefer, and it’ll do a phenomenal job. It’s not large enough to filter an entire house, of course. But no commercial filters you can buy is this powerful.

Still, smart positioning can save you some huge headaches. For instance, there’s probably at least a room or two in your home that needs more filtration than others. You can also, thanks to the small size, move the purifier around if needed. It doesn’t take long to set up, and you can have it purify multiple rooms over the course of the week.

Alternatively, you can set it to purify the air of your bedroom during the day, then move it out during the night.

Other Features and Filter Setup

The AirMax8L has additional features to make it worth your while. For one, it’s managed via touch control technology rather than blocky buttons. You only need to run your finger over the button services at the top of the filter to change settings or initialize filtering. There’s an additional security child lock incorporated into the control panel. This can prevent your kids from accidentally turning the filter on or off, potentially allowing pollutants to spread throughout a room. Then there are the intelligent filter replacement indicator lights. These give you plenty of warning before individual filters need to be changed or replaced.

This is the largest downside we could find in our investigation. The asking price is already fairly considerable. But you’ll also have to periodically replace the filters. This isn’t unexpected by itself; any single room air filters will need something like this at some point. The trouble is that this filter uses five layers of filtration rather than the usual two or three. Thus, replacing all of your air filters can cost a little more than you might initially expect.

Even so, the advanced air filtration quality is well worth the cost. This is especially true when you realize that it can relieve asthma symptoms and even stop mold from growing on your walls. To make things even better, the AirMax8L’s filters are entirely used before they need to be replaced. This stands in stark contrast to cheaper purifiers, which might only use the edges or corners of their sheets before demanding replacement. Each filter takes advantage of the general large air inlet area of the purifier chassis: 14.17” x 9.52”. With these filters, you get all of the value out of each purchase.

It’s also an incredibly energy-efficient purifier. At the highest speed, it only consumes 50 W of electricity. This lowers your energy bill relative to other single room air purifiers.

Quiet to Run

Not to mention its overall quiet operation; indeed, we found this filter to be quiet enough to run while sleeping. You can initialize a special sleep mode that lowers the noise to 28 dB at maximum, compared to the 59 dB you’ll get during max filtration mode. This control is a great extra function that has a lot of value for money. Thanks to this design, you can safely put this filter in a child’s room and know that they won’t be disturbed. The filter as a whole has a compact design that doesn’t take up a lot of space. You can easily set this on a table or shelf, or the corner of a room without it being an eyesore.

Finally, we’d be remiss without mentioning the extensive five-year warranty that comes with the purchase. It covers manufacturer defects and any breakdowns from regular wear and tear. It’s an excellent additional benefit that we feel brings great peace of mind to anyone who buys it. With the warranty, you’ll never need to worry about replacing the purifier on your own.

Final Verdict

At the end of our examination, we have to give the Okaysou AirMax8L Medical Grade Ultra-Duo Purifier high marks. Its air filtration properties are second to none, especially thanks to its five-layer air filtration design. Few air purifiers go to the comprehensive lengths that this purifier does. Not only can it scrub the air effectively, but it can do so without causing lots of noise. This eliminates one of the major problems with air purifiers and makes it easy to use in any room.

While you will need to purchase replacement filters from time to time, these filters will last longer than most others on the market. All in all, the Okaysou AirMax8L Medical Grade Ultra-Duo Purifier is a terrific budget option in the long run. We’d recommend it to anyone who wants to avoid springtime allergies or prevent pet hair from clogging the air.
