Pros And Cons Of Electrostatic Air Filters

 When it comes to an air filter for an HVAC system, there are mainly two types - electrostatic and disposable air filters. While most people prefer the latter as it’s easy to dispose of the filter rather than cleaning it, it’s best to use the electrostatic filter as it has numerous advantages. Today, we will discuss the pros and cons of electrostatic air filters that will help you decide whether or not they are best for your home.

What are electrostatic filters?

Before we jump into the advantages and disadvantages of electrostatic air filters, let’s take a look at what electrostatic exactly is. An electrostatic filter filters out air particles by means of static electricity. They are washable, metal type, and therefore, are commonly known as washable air filters.

 

Advantages of using electrostatic air filters at home:

Electrostatic air filters have a couple of advantages over disposable air filters; they are as follows:

Low cost - Although electrostatic air filters are expensive than disposable filters, they save money in the long run. You can wash and reuse them over and again for years.

Capture small particles - Electrostatic air filters capture particles using static electricity. Unlike disposable pleated filters, they also capture small microscopic particles.

Disadvantages of using electrostatic filters:

Like anything else, electrostatic air filters also have some disadvantages, mentioned below:

Limited efficiency - These washable filters become less efficient when they get dirty. In other words, you have to clean them frequently to receive clean, filtered air.

Less effective with increased airflow - When the airflow velocity is high, electrostatic filters are not very effective at filtering out air particles. That’s because electrostatic ally-attracted particles get ripped off of the collector when the airflow is increased.

Now you know all pros and cons of electrostatic air filters. If you want to cut the expense of changing air filters every now and then, electrostatic filters are the right choice for you.
