MERV (Minimum Efficiency Reporting Value) ratings measure how effective a filter is at capturing particles. A higher MERV rating means better filtration. For most homes, a MERV rating between 8 and 12 is sufficient.

Yes, a clogged filter restricts airflow, which can cause the system to overheat or freeze, leading to possible damage and costly repairs.

The filter size is usually printed on your current filter or in your HVAC system's manual. Common sizes include dimensions like 16x25x1 or 20x30x1.

Pleated filters are more efficient at trapping particles due to their larger surface area. Non-pleated filters are often cheaper but don’t capture as many contaminants.

Yes, filters with higher MERV ratings capture smaller particles like pollen, mold spores, and pet dander. However, using a filter with a MERV rating that’s too high can restrict airflow and strain your system.

Yes, regularly changing your filter allows your system to run more efficiently, which can lower energy consumption and reduce utility bills.

Yes, during high-usage seasons like winter and summer, your system works harder, so it’s important to change the filter more frequently.

Most filters are disposable and should not be reused. Reusable filters exist but require regular cleaning and are less common in residential systems.

Forgetting to change the filter can lead to poor air quality, reduced system efficiency, higher energy costs, and potential damage to the HVAC system.

Yes, a clogged filter can reduce indoor air quality and allow more allergens, like dust and pollen, to circulate in your home, worsening allergy symptoms.

Yes, homes with pets may benefit from higher MERV-rated filters designed to capture pet dander and hair, or special “pet filters” that are more effective at reducing pet-related allergens.

Electrostatic filters use static electricity to capture particles. They are typically reusable and can be washed. They may be more expensive initially but can save money in the long run if well-maintained.

A higher MERV filter can reduce airflow if it’s too dense for your system. It’s important to use a filter within the recommended MERV range to avoid putting extra strain on the system.

Most residential HVAC systems are not designed to handle HEPA filters, which have extremely high filtration levels. Installing a HEPA filter in a standard system could restrict airflow and damage the system. However, there are portable HEPA air purifiers that can complement your HVAC system.

Standard HVAC filters do not remove odors. However, some filters are infused with activated carbon, which helps absorb odors from cooking, smoke, and pets.

High-efficiency filters, like those with higher MERV ratings or HEPA filters, capture more and smaller particles than standard filters, improving indoor air quality. However, they may also reduce airflow if not suited to your HVAC system.

No, HVAC filters vary in size, material, MERV rating, and design. It’s important to choose a filter that fits your system and meets your indoor air quality needs.

Even if you rarely use your HVAC system, it’s still a good idea to replace the filter every 6-12 months to prevent dust buildup in the system and maintain air quality.

Most disposable HVAC filters cannot be recycled due to the materials used (such as synthetic fibers and cardboard). It’s best to dispose of them in the trash unless the filter or manufacturer specifies otherwise.
