MERV stands for Minimum Efficiency Reporting Values and is an industry-created
standard that evaluates the efficiency of air filters. The MERV rating of
any particular air filter ranges on a scale of 1 to 16, with a filter rating
1 being the least efficient and a filter rating 16 being the most efficient.
While it is important for the quality of the air in your home to choose the
most efficient filter possible, it is not always as simple as buying a filter
with the highest MERV rating. Because the pores allowing for air flow in
a highly-rated MERV filter are very small, the filter creates more resistance
against air flow and may put too much pressure on the fan of your furnace
or air conditioning unit. It’s important to choose an air filter with
the highest MERV rating that your particular unit will allow for maximum
air flow. Information about specific MERV ratings and recommendations for
your furnace will generally be included with the documentation that came
with your system.
We recommend choosing an air filter with a MERV rating between 8 and 11 for
most residential furnace and AC units in order to adequately remove airborne
contaminants. If your system can handle a filter with a higher MERV rating,
you may wish to use a filter with a rating of 12 or 13 for even greater contaminant
removal. However, it’s important to remember that filters with a higher
MERV rating must be replaced at least every three months to avoid restricted
air flow and negative effects on your furnace’s performance.

The All Filters Odor Eliminator filter uses a revolutionary carbon filter media called Gray Matter to efficiently remove household odors without reducing the overall air flow. The Gray Matter media works by reducing the average carbon granule in the filter to maximize total surface area. The smaller granules create more outer surface area for odors, fumes, and other air contaminants to adhere to, greatly increasing the filter’s efficiency.
The lightweight, durable filter fits into existing filter housings to provide guaranteed odor control without the need for expensive re-fittings or fans.
The carbon media is also resistant to moisture and microbial growth, keeping your household air safe from re-contamination.
This valuable filter provides efficient, safe odor control at a price that competes with standard pleated air filters!

How do Lysol filters compare to the standard pleated filters?
The industry standard for evaluating HVAC and furnace filters is the MERV (Minimum Efficiency Reporting Value) system, which measures the ability of the filter to capture particles such as dust mites. This system, however, uses particles of a predetermined during testing. In real life, allergen particles can vary greatly in.
The asthma & allergy friendly certification standard ASP-08-03/101, however, differs from other evaluation systems like the MERV system in that it measures the filter's ability to capture particles of any, with a focus on allergen particles. With this new standard of testing, the filters are built and tested specifically with allergy sufferers in mind, to help you breathe easier in your home.

How do I find the dimensions of my air filter?
Most air filters have two sets of dimensions: Nominal and Actual. The
Nominal dimensions of your filter are the measurements you take yourself of the height,
length, and width of your filter. Nominal dimensions are rounded up to the
nearest 1" measurement and are the dimensions that most air filters are
sold under. For example, if your air filter measures 9.5" x 19.5" x 0.75", the Nominal dimensions will typically be 10" x 20" x 1".
To find the best fit for your filter, we recommend measuring the dimensions
of your existing filter and then looking for the closest match in Nominal dimensions.
Height and length measurements are interchangeable, so a filter
with measurements of 16" x 25" x 1" may also be listed
as 25" x 16" x 1".
Your filter should fit snugly without having to be forced into place. Trying
to fit a filter that is too large into the required space can cause the filter
to tear or buckle and result in a loss of efficiency. If you notice air leakage
around the sides of the filter after installation, you may use gasket tape
around the edges of the filter to create a tighter fit.

How often should I change my filter?
Nominal replacement times will depend on the amount of particulate in each environment, including running time on the unit, the type of flooring in the environment, and the presence of people and/or pets. Generally, 1" air
filters should be replaced about every 3 months for optimal performance.
