Are Electrostatic Air Filters Worth the Time and Effort?

When you shop for filters, you may notice that there is quite a wide selection to pick from. The problem is, which one should you choose? The electrostatic air filter has become quite a popular choice for a lot of consumers lately, but the question is, are these filters really worth the time and effort?

For those people that are unfamiliar with the electrostatic air filter, an electrostatic air filter is a filter that cleans the air by the use of static electricity. This static electricity occurs naturally and is 100% safe for your household. When air blows through the filter, it blows through a series of static prone fibers which creates an electrical charge. This static charge attracts particles as they fly through your unit. To remove these particles from your filter, you’ll need to wash it regularly.

What are the benefits of electrostatic filters?

There are quite a few health benefits associated with electrostatic filters. Some of the benefits include cleaner air, decreased dust, reduced pollen and other pollutants and no dangerous ozone emissions released into the air. In addition to these benefits, electrostatic filters also:

  • Come with lifetime warranties
  • Hold an extreme amount of dust and other particles
  • Feature an anti-microbial filter media
  • Minimizes the amount of housework you have to do
  • Never have to be replaced
  • Washable
  • Can be resized for a small fee
  • High filter capacity

Available in a wide array of options (electrostatic furnace filters, electrostatic air filters, etc.)

What are the negatives to electrostatic filters?

So, although there are several benefits of the electrostatic filter, there are also several downsides to these filters as well. First, electrostatic filters must be removed from your system and be cleaned thoroughly at least once every 4 to 6 weeks. This tends to become a hassle.

Second, electrostatic filters simply do not work as efficiently as most pleated filters.

If you sufferer from severe allergies, you may want to choose another kind of filter. Forth, they’re definitely much more expensive that other filters. However, it is a one-time purchase.

Now that you understand both the positives and negatives of electrostatic filters, it’s essential to compare and contrast them with the other filters on the market. By doing so, you’ll be able to choose the right filter for your needs.

When it comes to disposal filters, you have your chose between a few options. You have disposable fiberglass filters, disposable pleated filters and disposable electrostatic filters. There are several benefits to using disposal filters over electrostatic air filters.

Disposable fiberglass

They are also extremely cost-effective and are great for people who an apartment. On the bad side, they have no ability to clean the air, they do not help with asthma or allergies and they need to be replaced regularly. These filters will run you about $1 to $2.

Electrostatic filters vs. paper filters

Filters made out of cotton paper or paper fibers also have their pros and cons.

On the other hand, electrostatic filters are better suited for households that have asthma or have severe problems with dust. In addition to this, electrostatic filters last a lifetime.

Electrostatic filters vs. high-efficiency pleated

  5. When your filter is dry, reinstall it.

Is anyone using Electrostatic permanent filters. I am suspecting allergies are worse. As this article states it will not help with allergies which helps support my hunch. I am wondering if others are experiencing the same issue?
