Choosing the Right Furnace Filter For Healthier Indoor Air

When choosing the right furnace air filter, there is more to consider than just filter size. The design of the filter can make a difference in how effectively it cleans the air. Furnace filter efficiency is measured on the MERV scale, or Minimum Efficiency Reporting Values, which rates efficiency on a scale of 1-20.

Less expensive filters have a MERV scale between 1-3 are are usually constructed of disposable fiberglass. Around 1-inch thick, these filters are designed to prevent larger particles of dust, lint, and other debris from damaging your furnace. They do little to keep the indoor air clean.

Disposable, pleated furnace filters are the most popular option found in stores. These filters are made from polyester or cotton paper and will remove smaller particles like mold spores and dust mites. Because of their higher filtration rate, pleated filters should be changed frequently to avoid clogging and reducing airflow through the furnace. Pleated filters have a MERV rating of at least 6 and are more expensive than fiberglass filters.

The most effective air filters are disposable or permanent electrostatic air filters. With a MERV rating of 10 or higher, they are highly effective and are recommended in indoor environments with persons suffering from allergies or upper respiratory conditions.

  • Maxwell Plumb Does Your Home Need a Dehumidifier? Written by Maxwell Plumb

    During a typical New York summer the air can be hot and muggy outside, which can mean excess moisture inside. Excessive indoor humidity is not just uncomfortable, it can lead to unhealthy mold, musty odors and condensation that can damage wood surfaces and paint.

    In today's tight, well insulated homes, excess moisture can make your air conditioner work harder to keep the air cool and dry. To help keep the air dryer, a dehumidifier can be an effective solution.

    How does a dehumidifier work?
    As warm, humid air is blown across a cold coil by a fan, moisture condenses into liquid, which can be removed through a drain pipe. The dry air then passes over a warm coil and is added back into the room. Dehumidifiers are controlled by an instrument called a dehumidistat, which turns the unit on and off depending on the amount of moisture detected in the air. The level of moisture is controlled by a dehumidistat, which turns the unit on and off. A dehumidifier's capacity is measured in pints of water removed every 24 hours.

    Carrier Whole Home Dehumidifers
    A whole house dehumidifier is designed to work in conjunction with your home's heating and air conditioning system by monitoring and controlling the level of humidity. It operates quietly and is easily maintained by cleaning a filter.
