Merv 8 Air Filter Review

MERV 8 filters are the lowest we recommend for homeowners.

And depending on your personal needs (which we’ll go into below), it can be an excellent filter.

Some people, though, will need a stronger filter, like the MERV 11 or the MERV 13.

We’ve reviewed both of these higher-grade filters in the links above.

Who is the MERV 8 best for?

As we mentioned above, MERV 8 is the minimum standard air filter we recommend for residential use.

That said, to understand the MERV 8, it’s best to look at what it doesn’t protect against. If you have allergies or multiple pets, or other chronic breathing problems, you’ll be best served by going up to MERV 11 or MERV 13.

Or, if you are a smoker (or live with one), or if you live in a city that has smog, you should consider a higher rating, as well.

So what does MERV 8 protect against?

In short, MERV 8 blocks particles of 3 microns and larger.

These includes:

  • Dust
  • Pollen
  • Dust mites
  • Pet dander (unless you have more than one pet)

Cigarette smoke, smog, and general allergens would best be handled by MERV 11. While, if bacteria, mold spores, and even wood-burning fireplaces are a concern, then you’d need to look at MERV 13.

As you can see, much of which filter you need depends on your lifestyle and what kind of air you regularly come into contact with — or what breathing issues you regularly battle.

The most important part of a MERV 8 filter …

It’s important that you get the right filter for your needs.

But what’s even more important than that is this:

Regularly change your filters.

Even the best filters don’t last past their recommended use.

In fact, the average life of a quality air filter is only around 2-3 months. After that, your filter will begin to break down and will get clogged. This is true even if the best filters.

But we also understand that it’s really easy to forget to change your filters regularly. That happens to most of us.

The problem is when you do forget to change your filter, especially if it goes on for month after month, you’re greatly reducing what your filter can actually block. And if your filter gets clogged from not changing frequently enough, then it’ll put extra strain on your HVAC system — which is an expensive repair.
