Welcome to our forum.
The biggest questions with filtration are-What is the square footage of the filter? - this is how much material the filter has in its construction- and consequently, how much debris it can take on.How many pumps are there? - every pump has to have two intakes. A filter counts for one intake. If it is a one jet pump spa, water will come through the filter and a bypass fitting at the bottom of the tub. If it is a two pump spa, you'll have three of those fittings along with the filter.Hope this answers some of your question. What kind of spa is it?
It is the Coleman 481 with two pumps. I can't seem to locate the square footage of the filter on their website.
To a certain extend square footage is marketing. Marquis for example until last year was at 100 sq ft of filtration marketing thought felt it meant more to the consumer than 70 which is what R&D wanted, they now use 70. Why ? better jet performance and the water stays just as clean.
why, that sounds like a marketing statement.
NWI, I own a Coleman 480, same spa except no lounger I believe. I've had no issues with good filtration.Coleman was also the first to have a "pre-filter", it's a round flat thin disk shaped filter that sits on top of the skimmer and grabs 95% of the debris that would normally go to the main filter. One just takes it out and rinses it off every couple three days and the result is that you don't have to clean the main filter as often as you would think. I get by cleaning the big guy once every 2 months and he is not that dirty. This prefilter gizmo is a slick idea and it really opens your eyes as to how much crap can get into your water.
