Furnace filters

A furnace filter, is it a filter like any other?

The efficiency of a filter for a hot air furnace with air conditioner / heat pump is dependent on its MERV rating, the efficiency measure of a filter. Depending on the environment, one filter is better suited than another. For example, the MERV rating for a residential furnace filter is lower than that of a filter for a pharmaceutical laboratory.

Criteria for selecting a furnace filter

An inefficient filter allows dust to pass which clogs the system. A too efficient filter, which allows too little air to enter, damages the furnace or the heat pump. In both cases, expect repair costs.

The market offers different types of furnace filters, to know what is appropriate, it is necessary to evaluate certain criteria:

• format: measure the dimensions of the filter of your system
• type: flat, fiberglass, pleated, electrostatic, etc
• Efficiency (MERV): industry standard determining the capacity of a filter. The higher the rating, the more efficient a filter
