PAPER VS. FELT

*RETURN HOME*

Paper is considered a lower initial cost item.  Although it can be cleaned, there is a low limit of the number of cleanings.  Higher overall cost.

PRICE

Can be competitive in price though sometimes higher initial cost.  If cleaning and reusing is achieved, overall cost will be less than paper.

Paper has a smooth surface, therefore less capacity than a fibrous felt material.  Shorter life span, more servicing and maintenance.

DIRT HOLDING 

More surface fibers on felt for greater dirt holding capacity. Longer operating time  before servicing, less maintenance.

In order for paper media to be equivalent to felt media in dirt holding capacity, you need four times the surface area.

FILTER AREA

One-fourth the surface area needed to be the same as paper.

Paper will rip and tear when wet and usually pleats will split, opening up a large area for bypassing.

STRENGTH

Stronger and will accept moisture.  Better equipment protection.  If bypassing occurs, it would be due to small holes that could eventually be covered by contaminant.

Although paper claims to be washable, it will lose strength and should not be cleaned more than 3 times.  After the first cleaning, paper loses 25% of dirt holding capacity and 10% after each additional cleaning.

CLEANING

Can be cleaned effectively by compressed air, vacuuming, or by washing in mild soap & water.  With regular maintenance, cleaning can be accomplished 10 or more times.

Pressure loss through paper is unpredictable.  Difficult to schedule proper shut downs for cleaning and replacing.

PRESSURE DROP

Pressure loss is gradual and one can predict reaching a maximum loss so shut downs can be scheduled.

A variety of efficiencies are available, but with some limitations.

EFFICIENCY

Efficiencies and a variety of media for chemical and temperature compatibility.
