Wondering which air filter is right for you? Our easy-to-use filter comparison chart will help you figure out the best filter for your home. The higher the MERV Rating of the air filter you select, the more dust, allergens and irritants will be filtered out of your air.

Additionally, if you live in a dusty or highly polluted area, you will want a filter that most effectively cleans your home's air.

📢 The frequency of air filter replacement depends on several factors, such as filter type, indoor air quality, household size, and whether you have pets. In general, it is recommended to replace standard 1-inch filters every 1 to 3 months. High-efficiency filters may last longer, up to 6 to 12 months.
📢 High-efficiency air filters, such as HEPA filters, can remove smaller particles and allergens. They are worth it if you or your family members suffer from allergies, asthma, or respiratory issues. However, they can also put additional strain on HVAC systems not designed for them.
📢 MERV (Minimum Efficiency Reporting Value) is a rating system for air filters that ranges from 1 to 16. Higher MERV ratings indicate better filtration. HEPA (High-Efficiency Particulate Air) filters are a specific type of high-efficiency filter that can capture at least 99.97% of particles as small as 0.3 microns.
📢 Some air filters are designed to help with odors by incorporating activated carbon layers that absorb volatile organic compounds (VOCs) and other odor-causing particles. Standard particulate filters generally won't address odors.
📢 To choose the right air filter, consider factors such as the size of the filter required by your HVAC system, desired MERV rating, any specific allergies or health concerns, and whether odor control is important. Also, ensure that the filter won't overly restrict airflow for your HVAC system.

"Case of 12 20x20x2 MERV 13 ordered and received. All filters seem in good condition and packed neatly in one box. No musty odour. Fit perfectly in my Nukit Tempest air cleaners. Delivery took 9 days ON-BC which is about 2 days longer than other shipping companies, but was completed to the door as requested and the time was not an issue for me."
"Pleased with product and service. We will buy again."
