Robotic Vacuum with HEPA Filter for Spotless Home in 2022

Robotic Vacuum with HEPA Filter for Spotless Home in 2022

If you suffer from allergies, or you live with furry friends, it is essential to have a robotic vacuum with a HEPA filter.

The HEPA filter keeps tiny particles in the vacuum cleaner instead of letting them float in the air. It can capture particles with a size of larger than 0.3 microns, which covers most of common pollutants in your home, such as dust, dirt, pollen, debris, stray crumbs, coffee beans, lint and pet hair.

If you use your vacuum every day, the filter tends to accumulate a lot of dirt. The filter might clog and lose its efficiency in trapping tiny debris. In order to keep your cleaning device working at its best, you need to know how to clean the HEPA filter.

In this post, we provide you with the most helpful information about robotic vacuums with HEPA filter.

1. How Does HEPA Filter Work in Robot Vacuum to Trap Dust and Dirt

To understand how HEPA filters work in a robot vacuum, you need to know how HEPA filters work. HEPA filters are usually made of chemical or glass fibers, which are capable of trapping 99.97% of airborne particles at least 0.3 microns in size.

HEPA filters have 3 main filtration mechanisms:

#1. Diffusion: For dust particles smaller than 1 μm, they do not move with the airflow, but move irregularly due to the impact of air molecules, also known as "Brownian diffusion motion". These particles are captured when they hit the filter fibers.

#2. Interception: Small and light dust particles move with the airflow and are intercepted when they pass across the fibers.

#3. Impaction: Larger particles cannot avoid the fibers and end up being embedded in one of them instead.

Three types of mechanisms allow the HEPA filter to capture both larger and tiny particles with a filtration rate of at least 99.97%.

So how does the HEPA filter work in the robotic vacuum? The vac pulls contaminants from the floor by rotating the brush and the power sucks them into the dust bin. Then the air is recirculated back into the house. If the vacuum cleaner does not have a HEPA filtration system, tiny particles and allergens will go back into the air as well.

A vacuum cleaner with HEPA filtration is ideal for reducing lint, cat litter, pet hair, dust bunnies and other allergens on the floor, especially if you or your family members suffer from some respiratory disease or allergies.

3. How to Clean the HEPA Filter in Robotic Vacuum

The HEPA filter will accumulate a lot of dirt and clog after a period of use. You need to clean it regularly to keep your robot vacuum in top-notch condition. Follow the below steps to clean the HEPA filter.

  • Detach the dust bin from the machine
  • Remove the HEPA filter from the dust bin
  • Use the equipped knife brush to separate the dust and lint form thefilter, or tap it lightly on the edge of the trash can to shake the dust off.
  • You can also wash it with cold water. Be careful, however, keep it dry for at least 24 hours and reinstall only when it’s completely dry.
  • Put the HEPA filter back into the dustbin
  • Reinstall the dustbin and close the vacuum cover

4. How Frequently Should the HEPA Filter Be Cleaned?

How often should you clean the HEPA filter? The professional engineer in Lubluelu advises that it should be cleaned every 1-2 weeks. But if you use the vacuum daily, you can clean it more frequently.

To enable your robot vacuum to work efficiently, it is a good practice to change your vacuum cleaner’s HEPA filter every 4-6 months.

Regularly maintenance can keep particles from being released back into air by your vacuum cleaner’s exhaust.
