AC filterIn many HVAC systems, the air filter is primarily designed to protect the system from dust accumulation and particles that could cause system damage, but higher-quality filters can also help to improve indoor air quality by removing, dust, pollen, pet dander and other undesirable particles. Air filters are classified by their MERV ratings, with a higher number representing better filtration.

  • Fiberglass filters: These filters are mostly intended to protect the HVAC system, and they typically have a MERV rating of 1 to 4, meaning that they only remove about 10 percent of pollutants. Most fiberglass filters are disposable, though some can be washed and reused.
  • Pleated filters: Pleated air filters have multiple folds to increase the surface area compared to fiberglass filters, and with MERV ratings of about 5 to 13, they can remove up to 45 percent of airborne particles.
  • High-efficiency media: These denser, thicker pleated fitters have MERV ratings of about 14 to 16 and can remove up to 85 percent of contaminants.
  • Electrostatic filters: These filters use an electric charge to attract particles, increasing filtering efficiency without slowing the airflow like dense high-efficiency filters.
  • HEPA filters: High-efficiency particulate air filters can remove up to 98 percent of airborne particles, but they are often too large and restrictive for use in standard HVAC systems. They are typically added with a whole-home air cleaning system.

As the MERV rating of a filter increases, the amount that it restricts airflow also increases. This can make the HVAC system work harder, increasing your energy costs. For most homes, an air filter with a MERV rating of between 8 and 10 provides a good balance between filtering efficiency and airflow. For improved air filtering, you may consider adding a whole-home air cleaner with either an electrostatic filter or a HEPA filter.

airborne pollenWith so many plants blooming, summer can be a difficult time for allergy suffers in Southwest Florida. While there is not much you can do about the pollen counts outside, there are several simple ways to control summer allergies inside your home, creating a comfortable retreat for the worst days.

Service the Air Conditioning System

Closing the windows and using the air conditioner when pollen counts are high is one of the best ways to control summer allergies, but if your system is not properly maintained, it can actually make the problem worse. Pollen, dust and other allergens can accumulate in the air handler, air filter and evaporator, and can then be distributed throughout you home when the system is used. Have your air conditioner inspected and serviced at least twice a year, which should include cleaning the coils, replacing the air filter and cleaning the air handler. Between service visits, change the air filter yourself every two to three months.

Use Hypoallergenic Linens

Choose hypoallergenic mattress covers, pillows, sheets and other bedding products, and wash them weekly to minimize allergens. Remove unnecessary clutter in your bedroom and closet to reduce the surfaces that can accumulate allergens, and when working outside, wash your clothes immediately, rather than storing them in a hamper, to eliminate excess pollen. Store seasonal clothes and bedding in sealed bags or bins to minimize dust and allergen accumulations.

Clean Often

Vacuum your home at least weekly using a machine with a HEPA filter, and dust often using electrostatic wipes or moist cloths. Whenever possible, use wood, vinyl or tile flooring, instead of carpets, to reduce allergen accumulations. When softer surfaces are desired, add throw rugs and take them outside monthly to beat the dust and pollen out of them.
