Small Footprint and Modern Design

At 8 inches deep the Max HEPA air purifier fits nicely against any wall. We invest heavily in design to bring you an air purifier you are proud to show off and not hide behind the couch.

Attractive neutral color and cool contemporary design that will match any décor. A conversation piece that blends well with your room.


No air by-pass so all the air is filtered. This is a huge feature and is one reason we have superior air filtration performance. This is due to the v-lock system that creates a seal around the HEPA air filter and locks the filter cover in place. If the air by-passes the air purifier filter you will not get the performance you need.

Smart Air Quality Monitor

Sensor keeps track of the air quality in your room. Automatically adjusts the fan speed if operated on auto mode.

Replacement Filter Indicator

Electronic display alerts you when it is time to check the air filters. The Max HEPA filter also has a color coded guide so you will know when to replace the filters to ensure you get fresh air.

3 Stage Filtration

Pre-filter, HEPA filter and activated carbon filter.

Quiet Operation

4 fan speeds


The Max air purifier cleans the air so you can breathe clean air to sleep and feel better to be your best. You get high-end air purification performance and a shrewd buy that works with your budget in mind. Comes with a cleanable pre-filter, HEPA filter and an activated carbon filter. The Max is Energy Star rated. 

With the v-hepa MAX we've redesigned the filters to make them larger. With both HEPA filtration and filter seals ensure you get the cleanest air possible. Better than HEPA-type filters. We make larger filters means they last longer (12 months of continuous use). Designed for room sizes up to 600 sq ft (20' x 30').

Simple to use, low cost to operate and quieter than other true hepa air cleaners in this price range. (Max HEPA at 34dB to 53dB as compared to 60dB-70dB). This is important as the noise level doubles with every 10dB of sound.

How the Max HEPA Air Purifier Provides Cleaner Air

Pre-Filter. The air first enters the pre-filter. This is where we remove the largest airborne particles. This enhances the filter life and performance of the other filters. The Max pre-filter is durable so you can easily clean with a vacuum cleaner if needed. Don't worrying about damaging it.

High-Efficiency v-HEPA Filter. The most effective type of air filter. Removes pet dander allergies, pet hair, mold spores, dust mites, pollen, allergens and other solid particles. Effectively removes 99+% of airborne pollutant particles that pass through the system. In addition, the Max removes other airborne impurities as small as 0.1 micron. Unique low air flow resistance technology makes the HEPA air purifier more powerful. Making it more effective compared to other air purifiers. We also added a seal around the filter to ensure the air does not by-pass the HEPA filter. This further provides cleaner air.

Activated Carbon Filter. A stand-alone carbon filter (not a small carbon pre-filter) that you need for air pollution and light odors. The activated carbon filter can remove some tobacco smoke odors however if you have a strong smoke smell you will be better off with the EJ Air Purifier for smoke. The EJ has more than 3 pounds of specially treated activated carbon for better air purifications in the removal of cigarette smoke and stronger odors. The EJ is also great for chemical gases, wildfire smoke and other gases. We've doubled the size of the carbon filter making it the best in class of air purifiers. This is not a thin carbon pre-filter. Rather it is about 1 inch thick. And we minimized the air flow resistance to cover the square footage in most rooms. The EPA states that a carbon filter "has the potential to remove most hydrocarbons, many aldehydes, and organic acids." Although as we state activated carbon is not effective for all gases and odors.

Anion. The nano piezo-electric ions makes your room more like a natural environment. A Journal of Hygiene study found negative ions improve efficiency of filters. Other studies (including those by the U.S. Dept. of Agriculture) found ions to be effective against dust.

While there are benefits to ions you have to be careful. We have written a lot about ozone and HEPA filters versus ionic air purifier. The Max has been tested by the top independent lab in the US. The results show no ozone in the test chamber. The Max is also certified by the California Air Resources Board. The negative ion on the Max can be turned off with the press of a button. This is an important feature that several air purifiers do not have. The last thing you want your air filtration system to do is create air pollution.

Night Mode. Don't want a bright light shining at night? Press and hold the power button for 3 seconds. The light around the power button will turn off. Press and hold the power button for 3 seconds to reactivate this light. Note: the blue lights in the center display will remain illuminated but they are not bright.

Intelligent Air Quality System. Gives you a visual sign of the indoor air quality in your room from the front of the air purifier. If operated in auto mode the fan speed will change depending on the air quality reading of the air pollutants. When first started the sensor may flash "AQS" for the first ten minutes. This is to show that the Air Quality Sensor is warming up and calibrating.
Note: the air quality sensor works in many but not all environments. If you feel it is not reading properly we suggest you run the air purifier on a manual fan speed.

Miscellaneous Air Purification InformationTo learn more we encourage you to read our customer reviews. It's an honor to help so many of you breathe clean air.

If you need a whole house air filtration system, we offer whole house air purifier bundles of the Max air cleaner so you can place one in each room. We also have our commercial air purifier and air scrubber line that can clean large spaces up to 1,700 sq ft.

If you are a smoker or suffering from second-hand smoke then you should see our EJ Air Purifier and ERIK650A Air Purifier. These have significantly more activated carbon to better remove cigarette smoke odors as well as the tobacco smoke particles.

If you are looking for an ultraviolet air cleaner then check out our Finn HEPA UV-C air purifier. It has a 5 watt UV-C light that removes airborne particles like mold spores, dust mites and pet dander with the added benefit of a UV lamp. If you care most about airborne allergens, the Max has a larger filter and stronger fan so it will clean the air better. Especially with larger square footage rooms.

Finally, if you want to learn all about air purifiers please see our Beginner's Guide to an Air Purifier. This guide covers everything from how a HEPA air filter, carbon-pre-filter and activated carbon filters work. We go in depth on the CADR ratings scale and how to make sure your air cleaner with work for your square footage. And how the MERV filter ratings work and compare a true HEPA filter to a HEPA-type filter. And how to choose a HEPA filtration system whether you need to remove dust mites, pet dander, pet hair, mold spores, pollen, tobacco smoke or even formaldehyde and other volatile organic compounds.

Troubleshooting. If the air purifier does not power on, remove the front cover and the filters and re-insert each. A safety switch ensures the filters are pressed all the way in and the cover is completely closed. In shipment the cover may open slightly or the filters may move a little. Also, if you press the Auto button, the fan speed display will reflect the air quality reading. Not the current operating fan speed so there can be a difference. We suggest setting the fan speed where you would like it and then press Auto. If the sensor shows 0 or 1 bars the fan speed will show as Silent, 2 bars is Middle, 3 bars is Strong and 4 bars is Turbo.

GREAT product March 15, 2018
Reviewer: Joe from Staten Island, NY United States  
I have only had the Oransi Max for a few days, and I can immediately feel the difference in the air in my home. It has great settings, a timer, and different fan speeds. The timer is important because you can set it for an amount of time you want it to stay on. It's easy to operate. The highest speed is about as loud as an air-conditioner. It's a steady sound though, so it provides some "white" noise.

I am really happy with it. I knew the minute I plugged it in, it was a great product. I highly recommend it. It's worth the money.

My review now after 3 weeks use March 13, 2018
Reviewer: Old Person from Pennsylvania USA  
Just to let everyone know that the Oransi Max is not made in USA but in CHINA.  I thought all products from Oransi were made in USA ,but I was incorrect.  Just unpacked units and I do hope they are worth the money.  Time will tell and I will report back.
My cleaning lady was my control. She has cat allergies and could only stay in my apartment for 1/2 hr and her helper had to finish the cleaning. Since I have had these purifiers running for 3 weeks, she came today and was surprised of the lack of dust, cat hair and she could stay in my apartment  and did not have any effects. GREAT GREAT GREAT!!  I do recommend this Air Purifier.

Miracle Purifier February 16, 2018
Reviewer: Joni from Biddeford, ME  
My brother had suggested that I have the air quality tested in my parents' apartment downstairs due to the difficulties my 89-year old father had breathing, but I thought it was related to his COPD until dad spent a few weeks in health care with no difficulties breathing.  
I did some homework, and after reading reviews and having discussions, I decided to order the #1 rated air purifier and see if it was going to work. I really had nothing to lose but a small amount of money compared to professional testing.  
Dad came home and a couple days later the Oransi purifier arrived. I immediately installed it in his bedroom.  I monitored it closely and saw it adjust automatically according to how air quality is and it has detected times where the air quality is less than desirable.
Since my father has been home, the air purifier on all the time in auto, my father has NOT had to take a Nebulizer treatment or inhaler! He is exercising without losing breath and getting stronger every day!
