With its wedge designed pleats and expanded metal reinforcement this filter, which is made in the USA, helps your air conditioning system perform at an optimum level.

  • 3. What is OGuard™ Technology with a FPLES Advanced Allergen Care Filter?

    In controlled laboratory tests the OGuard™ active ingredient included in this filter has been proven to be effective against a broad range of household odors, even tough fish odors. In fact, in a recent test against fish odors, OGuard™ technology was even more effective than baking soda. Both FPLES’ Energy Efficient and Advanced Allergan Care filters have Oguard and Microban.

  • 4. What is Antimicrobial Product Protection with an FPLES Advanced Allergen Care Filter?

    Today's high performance filters are capable of trapping many of the micro particles, including some as small as bacteria and fungi, and are designed to last up to 90 days. Unlike some inert particles which may be trapped in your furnace/air conditioner filter, bacteria and fungi are living organisms. Under certain conditions these micro organisms can multiply on unprotected surfaces, potentially resulting in odors and adversely affecting the performance of the filter media. The presence of antimicrobial product protection in the filter materials is not intended to affect airborne micro organisms, but can help reduce the uncontrolled growth of odor causing microbes on the surface of the filter material itself, where you need it the most. Microban® is not intended to affect airborne micro organisms.

  • 5. What is the Arm & Hammer filter?

    The Arm & Hammer Pet Fresh Odor, Allergen & Pet Dander Control air filter helps to reduce common household odors, even pet odors. The MERV 8 Air Filter has odor reducing technology built into the air filter media and can last up to 90 days.

  • 6. How Often Should I Change Air Filters?

    Local air quality surrounding your home and the environment within your home can significantly affect the useful life of your filter. Pets, painting, construction projects, etc. within the home can reduce filter life. For most Florida homes, FPLES recommends replacing your filter every 60 days or before they become completely covered with dust or other debris. This will help prevent harmful back pressure on your HVAC system. Even the highest-quality filter can't do its job right if it's clogged with a thick layer of particles. Changing air filters more frequently can also help to reduce energy costs. FPL Energy Services offers a reminder service that can be set up for 30, 60, or 90 day reminders that come via email or phone.

  • 7. What is a MERV Rating?

    MERV means Minimum Efficiency Reporting Value which was developed by the American Society of Heating, Refrigeration and Air Conditioner Engineers (ASHRAE). MERV values vary from 1 to 16. The higher the MERV value is the more efficient the filter will be in trapping airborne particles. Another consideration is air flow through your HVAC system. Leaving a dirty air filter in place or using a filter that has too high a MERV rating may result in low air flow and possibly cause the system to not function at maximum efficiency. FPLES recommends a minimum MERV of 8 and a maximum MERV of 11 for most residential applications.

  • 8. How Do I Decide Which Filter Is Best For My Home or Business?

    A/C FilterSmart® provides three options that fit most people’s needs. If your main concern is energy efficiency and protecting your AC system, our best value is our Energy Efficient filter. If you are concerned about airborne contaminants and allergies, try our Advanced Allergen Care filter. If it is pet odor you are concerned with then try the Arm & Hammer filter.

  • 9. How do I determine the size filter I need?

    The easiest way is to look at your old filter. Assuming it fits well it will typically have 2 sizes listed on the filter. The nominal size is usually larger or bolder and it is larger than the actual size. For example, a common nominal size is 20" x 20" x 1". The actual size of this filter is 19 3/8" x 19 3/8" x 7/8". Simply use the nominal size when ordering STANDARD sizes from A/C FilterSmart®. However, if you need a CUSTOM SIZE, order the EXACT size rounded down to the closest 1/2". If your filter doesn't have a size, or doesn’t fit well, temporarily turn off your AC unit and measure the air filter opening and subtract 1/2". Then round up to the nearest half inch and that is the nominal size. You should order filters based on the nominal size for standard size, but based on the actual size for custom sizes. If you have any questions, using our custom sizing guide or call us at 1-888-353-7451 and a specialist will help ensure you get the best size.

  • 10. Why are their 2 sizes listed on my filter?

    Filters usually are listed by both their "nominal" size and their "actual" size. "Nominal size" is the size most commonly seen on the filter borders, and "actual size" is the actual measurement of the filter itself and is usually a little smaller than "Nominal" size. AC FilterSmart uses "nominal" size for standard filters but actual size for custom orders.

  • 11. Can Regular Replacement of Air Filters Save Energy and Reduce System Maintenance Costs?

    Our air filters are suitable for most residential and commercial cooling systems that use 1” air filters of this type. High quality rigid frames are used to prevent unfiltered air from seeping around the filter and moving into your home or business. Our filters not only help protect your indoor environment, but also protect your cooling system. According to the United States Department of Energy “Keeping the filter clean can lower your air conditioner’s energy consumption by 5 to 15%.” For additional information on how air filters may save energy and reduce system maintenance costs please review information from the U.S. Department of Energy or Energy Star®.

  • 12. How do I install an air filter?

    Carefully, remove your A/C FilterSmart® filter from the shrink wrap and remove the paper wrapper. Then simply remove your old air filter and replace with your new one – make sure the arrow on the side of the filter matches the direction of air flow.

  • 13. Where do I find my air filter?

    For most AC systems in Florida, the filter is located in one of three locations. If the Air Conditioning return unit (blower) is located in a closet area, often the AC filter slides into a slot on the bottom of the AC unit. The second location is in a return located on a wall – there is a removable grill and the filter sits behind it. The final common location for filters is in a return grill in the ceiling. Don’t forget that if you have two inside units, you likely need to replace two filters at the same time.

  • 14. Does A/C FilterSmart® use fiberglass in their filters?

    A/C FilterSmart® filters and Arm & Hammer filter do not contain fiberglass. The filter media and frame are manufactured in America using new supplies, materials and components and that meet or exceed filter manufacturing standards.

  • 15. How much energy will you save changing your AC filter?

    This is impossible to determine for a specific home. However, the U.S. Department of Energy has stated that keeping the AC filter clean can lower your air conditioner’s energy consumption by 5% to 15%. * The US Department of Energy states, "Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%" A/C FilterSmart is offered and provided by FPL Energy Services, (FPLES), which is a subsidiary of NextEra Energy, Inc., and an affiliate of Florida Power & Light Company, (FPL).
