Frequently Asked Question

The 20x25x4 air filter is an ideal choice for homeowners and HVAC specialists alike. With four inches of thickness, it boasts a larger surface area to capture more particles, making it more effective and longer-lasting than the standard filters.


Not all furnaces can accept a 20x25x4 air filter, but those that do can reap the many rewards. Cleaner air, improved heating/cooling, and boosted energy efficiency are just a few of the benefits. If your furnace won't fit a 20x25x4 air filter, speak to a HVAC technician about resizing the filter chamber.


The 20x25x4 air filter offers MERV-11 rated filtration, which means it can capture up to 85% of particles between 3.0 and 10.0 microns. For context, that's about the same size as a human hair! What's more, these filters last 6-8 months, making it so that you won't need more than two a year. This is in comparison to the one-inch filters which need to be changed every 2-3 months.

When it comes to keeping your HVAC system in top condition, changing out your air filter is a must. However, it's important to ensure you get the right size and type of filter for the job. If the filter is too small, particles can enter the system; if it's too large, it won't fit and could create gaps that let contaminants in.


To determine the size, first look for the dimensions printed on the existing filter. Most filters have their length, width, and depth in inches listed on the side. For example, a common size is 16x24x1 – meaning the filter is 16 inches wide, 24 inches high, and 1 inch thick.


If the size isn't printed on the existing filter, you can measure it yourself. When measuring, take care to note the orientation of the filter to ensure you get the right size.


Getting the right size air filter is key to keeping your HVAC system running smoothly. If you're not sure what size you need, you can always contact one of the professionals at HELP! to help you determine the right HVAC filter size and type.


Is it okay to use a smaller air filter? The size of your current filter is essential. Don't buy a filter that's too big or small; it won't fit correctly and could let dirt pass through. If you're not sure what size to buy, ask your HVAC technician for assistance.


Air filters come in different MERV ratings. The higher the rating, the finer the mesh on the filter. But don't go beyond what your unit is designed for. If the mesh is too fine, your HVAC system won't have enough power to draw air through it and could damage your AC or furnace.


If you're considering changing to a washable filter, ensure your system can handle it. If you have the option of using a washable or disposable filter, take the time to research both before making a decision. Washable filters save you from buying replacements, but they cost more and require more effort to clean.

Does Size Matter? Absolutely! Using the right size air filter for your HVAC unit is essential to ensure it runs smoothly and you get the most out of it. If the filter is too small or too big, air will flow around the filter rather than through it, meaning not all of the air will get filtered.


To make things easier, we've created a helpful sizing guide. This guide covers the difference between nominal and actual sizes, how to find the right air filter size, how tightly your air filter should fit, where to buy air filters, and whether you can stack air filters if you need a thicker filter.


When it comes to installation, if you find yourself having to force or jam the filter into place, it's too big. On the other hand, if your filter does not come within 1-2 fingers’ width of all four corners of your air system handler’s slot or frame, it's too small.


Standard size filters not fitting well? Don't worry, custom size air filters are available from many online retailers, sometimes even at no extra cost. When purchasing a custom size air filter, remember the difference between nominal and actual sizes. Always specify exact measurements to ensure you get the right size.

You may be considering getting a pleated air filter for your HVAC system, and you’re probably wondering if it will restrict your home’s air flow. The simple answer is yes, pleated air filters will restrict air flow, but only to an expected degree.


It's understandable that people hear that pleated filters restrict airflow and think that it’s a bad thing, but that’s not the case. All air filters will restrict the flow of air to some extent, and as long as you get the right filter for the job, it’s totally normal.


When it comes to air filters, there are many types, such as media and HEPA filters, but we’re going to focus on the pleated fiberglass filter. This is the most popular type, and also the one that is most often questioned.


Yes, pleated air filters do restrict your furnace’s air flow. However, that’s what any filter does when it’s removing dust and pollutants from your home’s atmosphere. It’s important to choose the right filter for your needs so that it doesn’t overwork your system.


A lot of people are concerned that pleated filters can damage their unit because they restrict air flow, but that’s not true. All filters restrict air to some degree, because air has to move through the filter for it to remove particles from the atmosphere.


Doing your research and knowing what you want your filter to achieve is key. Putting a HEPA filter designed for a hospital into a residential home unit won’t be very effective.


So, to sum it up - yes, pleated air filters do restrict airflow to your HVAC system, but that’s to be expected from any filter. The important thing is to make sure you get the right filter for your unit and your needs.
