What You Should Know about Different Filtration Systems

Why should you care to learn about the filtration system in a central vacuum? Filtration systems are a major distinguishing factor between high quality and poor quality central vac brands. Our central vacuum reviews will help you understand the different filtration systems, how they work and why they matter when it comes to choosing the most appropriate central vacuum for your household.

Different brands have different filtration systems. The four basic types include:

  • The bagged filtration
  • Bagless filtration
  • Cyclonic Action system with a filter
  • True Cyclonic system with exhaust directed outside

Bagged Filtration

The bagged filtration system is certainly the most hygienic and efficient method of collecting your dirt once you vacuum. Central vacuums with bagged filtration use a cyclonic mechanism to sequester dirt from the air. As you vacuum your house, the dirt is directed to a plastic or cloth bag that is conveniently attached to the power unit.When the time comes to empty the bag, all you need to do is to remove the dirt bag from the power unit and throw it away. This means that you do not need to clean the dustbin.

The main advantages of choosing a central vacuum system with bag filtration are:

  • It thoroughly filters the air, keeping the dirt from being trapped in the motor. This extends the longevity of the motor.
  • It keeps you from interacting directly with harmful debris and dust; all you have to do is remove the dirt bag and dump it.
  • You only need to change the bag two times each year.
  • It keeps the receptacle and power unit area free from odors. Bagless filtration is also ideal if you are particularly allergic to dust.

Bagless Filtration

Some central vacuum owners prefer the bagless filtration system to the bagged one simply because they do not want to keep buying paper trash bags. The bagless filtration system uses a tornado mechanism to direct dirt into the dustbin, once you turn off the vacuum system. The tornado effect ensures that the filter does not accumulate the vacuumed dirt, in return keeping the motor system free of dirt clogs. Some things to watch out for in bagless filtration systems include:

  • Unlike the bagged system, the bagless filtration system requires outside ventilation because the exhaust air is not fully filtered.
  • Instead of emptying the canister just once a year, you need to empty it at least once every three months.
  • You will need to clean out the dirt, debris, and mold from the canister.
  • The vacuum’s effectiveness may decline gradually as the canister fills up.

Cyclonic System with a Filter

Some central vacuum systems come with a cartridge-like filter, which sorts out the dirt and debris, keeping it from being trapped in the motor. The rest of the debris goes into the canister. Here is what you should know about the cyclonic filtration system:

  • If you purchase a vacuum system with this type of filtration, you will need to wash out the filter regularly to maintain its efficiency.
  • Like the bagless filtration system, the cyclonic system may not perform effectively as the dirt and debris in the canister fills up. You will need to clean the canister at least 5 times annually to maintain efficiency.
  • The cyclonic mechanism requires you to vent the exhaust air outside to preserve indoor air quality.

Outside Venting Cyclonic Filtration

Vacuum systems that use the outside venting cyclonic filtration make use of the tornado effect to suck up dirt and debris from surfaces. The larger dirt particles go into the canister while the finer debris is filtered to keep them from clogging the motor, and then the dust is vented outward.

  • Because the dirt is vented outward, the same dirt may blow back into your house, thereby compromising indoor air quality.
  • You will need to clean the filter every time you vacuum to maintain the central vac’s efficiency.
  • Because this is a bagless system, you are bound to interact with moulds, dirt, and debris and foul smell as you clean the canister, which should be done at least 6 times annually.
