How The Max HEPA Air Purifier Provides Cleaner Air

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 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.

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 clean with a vacuum cleaner if needed however do not wash it in water.

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 particulates. Unique low air flow resistance technology makes the HEPA air purifier more powerful. 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 EJ120 Air Purifier. The EJ has specially treated activated carbon for better air purifications in the removal of cigarette smoke and stronger odors. The EJ120 is also great for chemical gases, wildfire smoke and other gases.

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.

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. It measures fine particles so may not record dust or mold that you can see (larger particles). If you feel it is not reading properly we suggest you run the air purifier on a manual fan speed (not Auto mode).

Miscellaneous Air Purification Information:To 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 EJ120 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.

Activated Carbon Filter:we suggest placing the air purifier in the room where you spend most of your time. For most this is a bedroom where the unit stays plugged in and runs 24/7 or whenever you are in the room.

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. We show 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.

How long does the pre-filter last? Pre-filter lasts up to 12 months but should be cleaned every 3 months.

How do I clean the pre-filter? Clean the pre-filter with the vacuum brush attachment of your vacuum cleaner.

How long does the real HEPA filter last? The real HEPA filter lasts 12 months.

When the HEPA filter light is illuminated, does it mean it’s time to replace it? The filter light will illuminate after 3,000 hours of run time. This light is an indicator to check the real HEPA filter.

How do I know when to replace the HEPA filter and activated carbon filter? There is a color code on the right hand side of the HEPA filter that shows how dark the filter media gets before it needs to be replaced.

How do I replace the HEPA filter?

1. Turn off and unplug the purifier.

2. Use the front cover removal tool and insert it into the uppermost side air intake slot. Gently push outwards against the back surface of the front cover until the top corner of the front panel pops open.

3. Repeat this process for the other side and then lift the entire front panel up and away from the main body, exposing the filter compartment.

4. Turn the 4 locks per the direction of the arrows to release the pre-filter. On the HEPA filter, hold the small ribbons at the top and pull the filter out. On the carbon filter, hold the small ribbons at the top and pull the filter out.

5. Re-insert the new filters by inserting the bottom portion first then pushing the top into place. For the front cover, interlock the bottom first and push the whole cover inwards at the top two corners to secure it.

What if I don’t have the front cover removal tool? You can use any non-conductive item such as the handle of a plastic utensil or wooden chopstick.

How to reset the HEPA filter light? Press and hold the Fan Speed and Anion buttons simultaneously until you see “CL” for Clear on your control panel.

What is the function of the Air Quality Sensor (AQS)? The AQS measures and displays air quality in 5 levels (Excellent, Very Good, Good, Standard, Poor). The line corresponds to the particle count as measured by the AQS. Each of the air quality sensor levels will display differently on your purifier.

Excellent: no bars

Very Good: 1 bar

Good: 2 bars

Standard: 3 bars

Poor: 4 bars

What if my AQS light is blinking? It usually blinks when first turned on until the machine warms back up, which can take up to 10 minutes, and then remains illuminated. If any buttons are pressed on the purifier while it’s warming up, the process will start over.

What if my AQS light is red and won’t change back to green? Clean the lens of any accumulated dust by lightly vacuuming the sensor located to the right of the power button.

What is the function of Auto Mode? In Auto Mode, the purifier will run at the lowest fan speed. If the AQS detects a change in the density of particles in the air, the unit will increase the fan speed. Once the AQS detects it has cleaned the dense particles out of the air, the purifier will return to the lowest fan speed.

What if my fan speed is not adjusting in Auto Mode? First, verify that the sensor to the right of the power button is functioning properly by lighting a candle and blowing it out toward the sensor. The purifier should immediately increase fan speed and then come back down again. If you do not have a candle, you can use a match or something with aerosol. If the sensor does not react, then reach out to Oransi customer service.

What is the function of the Anion Generator? The Anion Generator is a low-level and ozone-safe negative ionizer that freshens and balances the air by neutralizing a surplus of positive charges from TVs and computer monitors.

How do I turn on the Anion Generator? Press the Refresh button to turn this feature on and press it again to turn the feature off. When the refresh icon is illuminated, the anion feature is on.

What is the function of the Timer? This allows you to set a timer for how long the purifier will run and then shut off automatically. Press the Timer button to set the number of hours you would like the purifier to run. Each time the button is pressed, it will increase by 1 hour up to 12 hours.

What if my purifier does not turn on? The purifier will not operate if the filters and front cover are not placed properly.

1. Turn off and unplug the purifier.

2. Remove the front cover and all of the filters.

3. On the bottom of the unit, in the back right hand side of the frame is a safety switch — click this in and out 4 or /5 times.

4. Re-install the filters and ensure each is seated in its place.

5. Reinstall the front cover with the bottom edge first and push the whole cover inwards at the top two corners to secure it.

How can I clean the outside of my purifier? Use a clean, dry, soft cloth to wipe the external surfaces. Never use any chemical or harsh cleaners.
