An air scrubber is a portable device that purifies air. The device works by drawing in air from one side, passing it through filters, and releasing the purified air on the other side. During this process, the filters inside the device catch tiny particles in the air, such as dust, pollen, and dander. With the help of these devices, you can clean your indoor air and prevent many respiratory diseases. If you already own such a device, we recommend that you follow these tips to get the best results.
1. do not overload the pre-filters.
Make sure that you change the pre-filter regularly. The unit will not function properly if the filters are clogged. For proper airflow and long life of the primary filters and blower motor, do not overload the pre-filter.
It is better if you use high quality filters to reduce air resistance. They can also help prevent the air pressure drop when the filters have exceeded their effective life.
2. dispose of old filters properly
It is important to dispose of filters when they have reached the end of their useful life. Remember to wear gloves and a face mask before removing the filter from the unit. If you are not careful enough when replacing them, loose particles will fly back into the room air. Therefore, you should place the expired filters in a sealed bag and then dispose of it according to local regulations.
3. use activated carbon pre-filters
If you want to avoid unpleasant odors, it is better to buy a unit with activated carbon pre-filters. Unlike traditional carbon filters, these pre-filters are much more porous. Since they have a larger surface area, they are able to absorb a lot of odors.
The porous material allows easy passage for air, but the surface traps harmful contaminants. The moment these pre-filters become saturated, you should replace them as soon as possible.
4. adjust the air flow rate
If you want to capture most of the dust particles from the room air, you should set a lower airflow rate. The downside is that a lower airflow rate will not allow as much air to pass through the filters. Even if you increase the airflow rate, it won’t necessarily increase the efficiency of the unit. In fact, too high of an airflow rate will decrease the efficiency of these units. Therefore, we recommend that you follow the manufacturer’s operating instructions.
5. Clean your indoor air around the clock.
For proper air purification, experts recommend that air scrubbers should be left on around the clock. Since these units should be run at a lower airflow for greater efficiency, it’s a good idea to keep these units running even when you’re not at home.
6. HEPA Filters
Just because a filter media is HEPA certified doesn’t mean it can capture 99.97% of tiny air particles. The reason is that the size of these particles is above 0.3 microns under real conditions. Therefore, you should invest in HEPA certified filters as they are made of the right material.
For efficient filtration, the airflow rate should be 250 m3/hr. If the airflow rate is higher, proper filtration cannot be achieved. In other words, a lower airflow rate is recommended if you want to clean your indoor air in an efficient way.
