Water Filtration Vacuums: Are They Better Than HEPA Filters?

Vacuums that use water filtration or simply water vacuums are becoming the new trend of vacuum cleaning technology.

There’s a good chance you’ve never heard of this type of unit or technology before, as it’s still relatively new and not quite the industry standard (at least not yet).

So, let’s take a closer look at what they are and what makes them different to traditional vacuum cleaners?

What Are Water Filter Vacuums

The difference between a regular vacuum unit and a water filtration vacuum cleaner is the filter technology and how it collects the dust after suction.

A regular vacuum cleaner will suck dust / debris into a bag or dust bin. The air has to flow out the vacuum cleaner to allow for continuous suction. However, you don’t want the out flowing air to blow out the dust that’s just been vacuumed up. So a HEPA filter, made from cloth prevents that from happening.

Water filtration vacuums work much in the same way. They suck dust throughly, however, rather than collecting the dust in a bag or bin, they use water as the filter instead.

HEPA: An acronym for high-efficiency particulate absorbing, is a filter that’s specifically design to absorb 99.9% of particles equal to 0.3 μm. The efficiency increases for particle diameters both less than and greater than 0.3 μm.

How Exactly Do Water Filter Units Work?

When suction takes place, instead of dirt going into a bag or bin, it gets trapped inside the water.

As a result, clean air passes through the water (without dust / debris) and back out the machine to allow for continuous uninterrupted suction.

Essentially, when dust has water added to it, it prevents it from rising up in the air and back out the machine.

Once the water no longer looks see-through, it’s time to empty it out and refill with fresh water.

Are Water Filters Better At Filtering?

As much as I wish there was a clear cut answer, it depends on preference. For my perspective, with all things being equal, I’d say the water filter vacuum provides more advantages than standard filter.

Let’s take a look as some pros and cons to give you a reference, so you can make up your own mind:

Pros of Water Filtration Systems

  • Less mess while emptying
  • Wet & dry cleaning capabilities
  • No filter clogging or cleaning
  • Holds more dirt, therefore less emptying
  • Less allergen release into the air
  • Deals with pet hairs better
  • Better for people with allergies

Cons of Water Filtration Systems

  • On average a more expensive unit
  • The water makes them heavier units
  • Few options in the market to choose from
  • May require more cleaning out of water unit

Available Type of Water Vacuums

As it stands, there are only 2 types of water filter vacuum cleaners on the market.

Those are the canister and upright types, with the canister ones being the more popular of the two.

Water canister have a lower center of gravity, making them easier to manoeuvre.

Water upright machines typically have their tanks higher up, which ultimately means the mass of water being higher up. This makes it harder to manoeuvre and control the machine.

Cleaning Up Final Thoughts

Although there aren’t many options on the market, these vacuum cleaners are growing in popularity, leading me to believe, with further technological improvements, they will become the standard.

Does vacuuming trigger your allergies? Are you tired of having to empty your bin and clean out your filter to maintain suction? Then it’s time to try a water filtration vacuum!
