• MERV 5-8: More effective at trapping smaller particles like mold spores and pet dander.
• MERV 9-12: High-efficiency filters suitable for households with allergies.
• MERV 13-16: Superior filtration, capturing smoke and bacteria, ideal for sensitive environments.
• MERV 17-20: HEPA filters that provide the highest level of filtration, often used in hospitals and clean rooms.

Types of 16x20x1 Furnace Filters

Basic Pleated Filters

Basic pleated filters are the most common type found in homes. They provide decent filtration for everyday dust and allergens. Brands like Filtrete and Honeywell offer these filters, which are typically rated at MERV 5. They are economical and ideal for general use.

High-Efficiency Filters

High-efficiency filters, rated between MERV 11 and 13, are designed to capture finer particles. They effectively trap allergens, smoke, and other contaminants, making them perfect for homes with pets or allergy sufferers. Brands like Discount Filters and Honeywell sell these types of filters, providing long-lasting performance.

HEPA Filters

HEPA filters are known for their high efficiency, with ratings of MERV 17 or higher. They are capable of trapping 99.97% of particles as small as 0.3 microns, making them the best choice for individuals with severe allergies or respiratory issues. Brands like FilterBuy and Honeywell offer HEPA options, ensuring clean air throughout your space.

Activated Carbon Filters

Activated carbon filters are primarily used for odor removal. While they may not have a MERV rating, they excel in absorbing volatile organic compounds (VOCs) and unpleasant smells. Brands such as Discount Filters provide these filters, which can be used in conjunction with other filter types for comprehensive air quality management.

Applications of 16x20x1 Furnace Filters
