One way of addressing indoor air pollution is by ventilating your home with fresh, clean outdoor air. But this method is not effective at all times. According to EPA, ventilating your home is usually limited by weather conditions and the level of pollutants.
For example, if you live in the city, ventilating your home means the introduction of smoke from traffic. In other areas, you may be exposing your family to VOCs, soot, and other pollutants.
What this demonstrates is that ventilating your home is insufficient when it comes to removing pollutants from the air. The best solution proposed by EPA and air quality specialists is an air purifier. A good example is the Oransi Max Air Purifier.
This purifier can clean the air of bacteria, mold spores, dust, pet dander, and other allergens. Best for the living room, bedroom, and office, it changes the air every 20 minutes, assuring you of clean air.

In-depth Review of Oransi Max HEPA Air Purifier:
Ultrafine particles get introduced into your home from a variety of sources. They include chimneys, tobacco smoke, and car exhausts. If you have improperly installed appliances in your home, such as woodstoves, emissions can pollute the indoor air.
Besides the pollutants above, small biological particles like airborne bacteria, mold, and viruses can get in your home. To trap these micro-organisms, you need a quality air purifier like the Oransi Max.
Here are some of its amazing features.
Quiet Operation
If you are looking for an air purifier with a noise level of 34 dB at the lowest speed, then this is for you. The Oransi Max features four speeds and an auto mode. At speed 1, the fan produces 34 decibels, at speed 2, it delivers 41 decibels, and at speed 3, it produces 47 decibels.
At the highest speed or turbo mode, the air purifier delivers 53 decibels. To better understand how quiet it is, let’s compare our air purifier with other sources. At 34 decibels, this air purifier’s noise level is comparable to soft music, whisper, or leaves rustling.
If you up the fan speed to 41 decibels, this is slightly higher than the average home noise. Even at fan speed 3 or 4, the air purifier is still quiet. In fact, you can have a normal conversation or listen to music, and the running purifier will not interfere.

Airflow Rate
At speed 1, it has an airflow rate of 147 CFM, and at speed 2, the flow rate is 185 CFM. At the highest fan speed, Oransi has set the airflow rate at 245 CFM.
At the maximum speed, it can clean a 920 square feet room twice an hour. As such, you and your family can enjoy pure air, day and night. It gets even better.
4-Stage Filtration System
Another feature homeowners will love about this air purifier is the 4-stage filtration system. Composed of a washable pre-filter, a HEPA filter, an activated carbon filter, and an anion ionizer, the purifier removes 99% of air particles.
As an upgraded version to the discontinued Oransi v-HEPA Pro purifier, the purifier can deliver clean air every 20 minutes in a 600 square feet room. The washable pre-filter is the first defense against pollutants in the air.
The air moves through the washable pre-filter, where it removes large particles. These particles include dust, pollen, and pet dander. Thanks to the pre-filter, it enhances the performance and durability of the other filters. It recommends cleaning the pre-filter every 3 months. To clean and maintain the pre-filter, wash with a damp cloth or vacuum it.
After the pre-filter, you have the High-efficiency HEPA filter. This filter traps and removes particles measuring 0.3 microns or larger. With a cleaning efficiency rating of 99.97%, this filter lasts for a year.
The air passes through the activated carbon filter where gaseous pollutants like cooking odors, VOCs, and gas fumes get absorbed. This means, the activated carbon filter purifies the air and ensures that VOCs and other harmful fumes do not travel into your lungs.
Just like the HEPA filter, the activated carbon filter also lasts long. If used continuously, the v-HEPA filter lasts for 12 months.
The last stage of the filtration system is the nano piezoelectric ionizer. This ionizer releases negative ions into the air, which helps to trap airborne impurities.
Basically, the high-density negative ions attach themselves to airborne particles, making them larger. This makes it easy for the filtration system to capture and remove the particles. What you need to know is that the ionizer releases a negligible amount of ozone.
In fact, the California Air Resources Board certified the air purifier as an ozone-safe.
Sleek Design
As a quality-built air purifier, it comes in a vertical design, with front and side intakes and an outlet at the top. Made of ABS materials, glossy finish, and white in color, it’s durable and offers years of long use.
Thanks to its compact design (17 inches wide by 22 inches high by 8 inches deep), it’s ideal for rooms measuring no more than 600 square feet or 20 feet by 30 feet. What we liked about this purifier is that the sleek design makes it more attractive than other models.
As such, it can pair well with your home decor and not become an eyesore.
Air purifiers use multi-stage filtration systems to purify the air in your home. If it lacks a quality build, some of the dirty air passing through the filters will escape. To ensure this does not happen, Oransi equips all its air purifiers with V-Seal and V-Lock technology.
Wondering what this technology consists of? It consists of a special seal. Oransi surrounds the air filter with this seal locking the filter cover in place. As such, they ensure unfiltered air does not escape. To strengthen the purifier’s cover, Oransi also uses insulated V-Lock technology around the edges of the filters.
Other Features
The air purifier has a coded monitor. This monitor keeps track of the air quality in your home. If the sensors detect contaminants in the air, they will adjust the fan speed automatically to fast track the removal of pollutants. In turn, the air purifier distributes clean air in your home.
You also have the filter replacement indicator. These indicators alert you when it’s time to replace the filters.
Other controls on the electronic display include a timer, anion, and the power button. Air quality specialists recommend that you run the air purifier 24/7. At night, the bright light may interrupt your sleep.
To turn it off, press and hold the power button for three seconds. To re-activate the light, repeat the process.

Questions and Answers:
Q. When you turn on the auto mode, does it mean you can leave the air purifier running all the time?
A. Yes, the auto mode controls the fan speed of the air purifier. This feature works together with air quality sensors. If the sensors detect contaminants in the air, the air purifier changes the fan speed to clean the air efficiently.
Q. How often does the air purifier change the air per hour?
A. The manufacturer recommends a room size of 600 square feet for the air purifier. But if you place it in a 370 square feet room, the air purifier can change the air five times per hour. Use our ACH calculator to find out the air exchanges in your room.
Q. Do I have to place this air purifier in the center of the room for it to work efficiently?
A. No, you can place the air purifier anywhere in the room. Thanks to the side and front intakes, the air purifier sucks in dirty air and releases clean air at the top. The manufacturer recommends not placing the purifier close to objects that block the front or side intakes.
Final Thoughts
The Oransi Max air purifier features improved seal technology, lasting filters, and air quality sensors. Thanks to these features, it can purify moderately large spaces. As such, it offers a higher level of purification, unlike comparable models.
So, if you are looking for an air purifier that is super-efficient and saves you on filter replacement, we recommend the Oransi Max air purifier.
