What does it mean?

Do you ever check or compare the square-feet measurement of a filter before buying? 

We all probably check the price and that it is the correct size and fitting, but the square-feet?

What does the square-feet figure relate to?

In simple terms, if you opened up the filter and spread the actual filter material out on the floor, and then multiplied the length by the width in feet, this is the area measurement in square feet.

You might be surprised how much filter material there actually is!

There are a number of important factors that go into the making of a quality Darlly filter, the area (square feet) is just one of these.

The main items are the quality of the filter material and the amount of it. Not only is the ability of the filter material to filter out the contaminants and debris, both visible and invisible to the naked eye important, but also the physical integrity and durability are vitally important to enable the filter to withstand repeated cleaning cycles and to ensure a long and efficient service life. 

Read our ‘How to clean a filter’ topic for more information about cleaning.

Remember, if the filter material is holed, ripped or torn it will not be doing its job and must be replaced. The filters also help to protect the pumps from debris.

For a given hot tub, the greater the area of the filter material, generally the time between filter changes will be longer, thus reducing the maintenance downtime of your hot tub and making your life just that little bit easier!  

The answer, we now know, to the question ‘Is the square-feet measurement of a filter important?’ is a definite YES!

Make a quality decision, choose a quality Darlly filter and enjoy the benefits.
