Finding a furnace filter for a mobile home must have been tricky. Until now, we’ve heard many tiny homeowners complaining about the lack of small size filters. Thanks to Miller Polly, a company that has focused on designing this unit, especially for mobile homes. So, let’s find out more about the benefits of this unit in the following paragraphs.


This furnace filter by Miller Poly measures about 19” x 54”, and it comes in a pack of four for better convenience. So, we don’t have to worry about ordering new sets every two or three months. It was tricky for us to find a filter that would fit the furnace door in our mobile home. 

However, we had to trim the edges slightly to ensure that it fits correctly. Since it’s made to be used in our mobile homes, we had to mount it on the furnace door with the help of built-in retainers. 

One drawback that is worth mentioning is that the manufacturers have not mentioned about the MERV rating. But there is no issue with the efficiency, because the filter has been coated with a sticky substance to catch more dust.

If you had checked out some of the older filters, you must have seen that fiberglass was one of the most frequently used materials. And the the top-rated options that come under this category is the PrecisionAire Nested Fiberglass Filter by Flanders. You don’t have to extend your budget to purchase this unit, which makes it a suitable choice for many.


We have been using fiberglass filters for over a decade, and finding such an affordable piece has been a great advantage. It’s available in a set of few standard sizes, which makes it easy to order for the right size. 

The MERV rating of 4 is pretty minimal, but we generally don’t face too many issues with the accumulation of dust or debris around the house. So, even if the rating is low, it helps to keep the indoor air quality in an optimal state. We can’t recommend this unit for homes with too many pets or if people are suffering from allergies.


Nevertheless, it features a quality filtering medium that is made with continuous filament spun glass. The filter frames are constructed with chipboard, makes it easy to install the unit.

Best Furnace Filters Buyer’s Guide

Here’s a list of the factors that you need to consider before purchasing a furnace filter:

  1. Filter size

You need to opt for a filter that fits accurately into the system to ensure better efficiency. To find the furnace filter size, you should check out the manual, or it might be highlighted along the edge of your new device.

  1. MERV rating

This is another important factor that you need to consider because the MERV rating determines the system’s efficiency in trapping dust and other pollutants. The higher the rating, the better is its ability to remove dirt and contaminants. Try to select a model with the highest MERV, which your HVAC unit can comfortably accommodate.

  1. System specifications

Although the ideal choice for filtering out pollutants is generally the HEPA filter, many of the residential units can’t handle it. But, if you don’t pick the right filter for your HVAC unit, then it can damage the system and drive down the energy efficiency. So, it’s always advisable to check the manufacturer’s instructions before placing the order.

  1. Cost

If you buy a high-quality filter, then you’ll receive a good return on investment over time. However, the low-cost filters require frequent replacement, which further adds up to make a huge budget.

Final words

We understand that deciding as to which model will be the best for your home must have been a bit challenging. Especially with the range of available options. 

But it’s essential to go through the buyer’s guide carefully to ensure that you make the right choice. After all, putting in a little effort to pick the best furnace filter goes a long way in reducing your expenses. 

And mainly it helps to protect the air quality in the house. So, what are you waiting for? Go ahead and place the order.

Till next time!
