One of the main things is to have a good air filter on your furnace or HVAC system.

All furnaces have a filter that is meant to keep the system clean from debris that can build up and block air flow.

Having good air flow in a HVAC system is important for it to regulate the temperature. If the air flow is blocked the temperature inside a furnace will rise until a High Limit Switch shuts it off.

Most everyone knows that the filter needs to be replaced every 1-3 months depending on how much dust and other debris is in the air.

The right furnace filter can improve the air quality of a home and reduce allergies.

Cheap low cost filters are commonly used and work well enough to keep debris from clogging up a HVAC system but they do little in cleaning the air in a home.

Filter are rated with a MERV or MPR rating that measures the particle size that can pass through.

The smaller the particle size that can pass through the better in keeping the air clean. There is also electrostatic filters that build up an electrostatic charge which dust clings.

Allergy surfers should get a filter with a Merv rating of at least 9-12.

How To Buy a Replacement Furnace Filter

Summary
Having a quality furnace filter will greatly improve the air inside a home.

How often a filter is replaced depends on the environment. For example those who live in a desert with a lot of dust will need to change it much more often then less debris in the air.

Units that have good Merv ratings also have smaller particles sizes that capture more which in turn often need replacement much sooner than less effective units.

While they are usually changed every 2-3 months each home is different and may need changing more often for the best results.

Disposable units while cheaper initially can cost more after long term use since they need to be thrown away once dirty.

Washable are more expensive to buy but can be cheaper after long term use since they can be used over-and-over again.
