Frequently Asked Questions (FAQ)
What are the best rated furnace filters?
Cleaning or replacing furnace filters is extremely simple, but it can save you a lot of money and frustration in the end. These filters are specifically designed to filter out any particles of dirt, dust and other airborne materials indoors.
Furnace filters are a common feature in most homes today. They are also a very necessary one too.
Dust and dirt can make their way into your home from a number of different sources like your neighbors zucchini plant, construction vehicles, even the outside air. If you do not do anything to keep these pollutants out of your house, they will sit there quietly destroying everything in their path.
To ensure that your furnace filters remain effective, they should be replaced every 3 to 6 months. If you do not have all the time to do that yourself, you can always call a heating and cooling service provider to do it for you. This is a much better approach in terms of both cost and time.
What is the best furnace filter for viruses?
The best furnace filter for viruses should have a very high MERV rating. The higher the MERV rating, the more effective the furnace filter will be against viruses. The high-end Lennox brand furnaces are among those that offer very high MERV ratings – up to 21 (the higher the rating, the better the filtration) – which is ideal for those that are among the 10% of people who are considered extra-sensitive.
What is the best MERV rating for furnace filters?
A higher MERV rating indicates better filtration, and, almost invariably, lower air flow.
So, higher is better on both counts, right?
Well, maybe.
It depends on what you need the furnace filter to do.
A lower MERV filter will have fewer pleats.
These pleats reduce the surface area of the filter, so, a lower MERV will have less filtration capability, but it will be a higher-flow filter.
A higher MERV filter will have more pleats.
These pleats add surface area to the filter, so, a higher MERV will have better filtration, but it will be a lower-flow filter.
So, what is the right MERV rating for you?
There is no straightforward answer because it depends on what you need.
