Spa Filters & Hot Tub Filters Lifespan - The Truth Will Surprise You!

You could possibly well happen to be misled about spa filter & hot tub filter maintenance & indeed how much effort required in maintaining your spa & hot tub water quality generally! Don't feel bad about it because we estimate that 80% of most spa & hot tub purchasers will be in a similar boat. The 'nice' salesman who sold you your spa or hot tub wants prospects to believe that ownership is often a totally painless process - they just don't want 'obstacles' to look that may put people off. And of course it's miles more romantic to paint a picture of sipping champagne on balmy nights than put on the detail of spa & hot tub maintenance! So why don't we just claim that they 'play down' the value of spa filter maintenance, the frequency of which they desire removing & rinsing, deep cleaning with cartridge cleaner & how long your filter/s is bound to last.

To be fair, the common lifespan of an 'Pleated Reemay Cartridge' spa or spa tub filter is usually quoted being 12 months roughly inside spa, spa tub and pool industry. In fact this is more accurate for any 'Pleated Cartridge' POOL filter, however the statement has just 'carried-over' to incorporate spas & hot tubs as well. The filters are made from a similar (Reemay) material but there are many significant differences between a Pool & Spa or spa environment:-

1. The amount of water 'per person' in a small domestic pool is really a lot larger than in a very hot spa - a small family pool with say 20,000 litres of water 'shared amongst' a household of 6 gives greater than 3,300 litres per person, an average six seat spa or spa with 1,300 litres of water gives approximately 200 litres per person - thus you would need 100 people within the small family pool to be similar to having 6 within the spa tub! Positive change!

2. The temperature that the hot tub/spa operates at is significantly greater than that of a swimming pool. This results in a myriad of other issues, not least that will be the hot tub's capacity to breed bacteria in a much accelerated rate, 'strip-off' body lotions, creams & spray-tan & remove all of that latent detergent still 'hiding' within your newly laundered swim-wear. Adding coagulant goods like foam down, sparkle etc. only serves to raise cleaning frequency and further reduce filter life. The answer could be the usage of a scum absorber much like the new Zorboid product.

The web result of these factors could be that the lifetime of a spa filter is really a much harder one in contrast to a swimming pool filter, it is hardly surprising then that their endurance is considerably shorter. Recent research from G.E. Water (a part of General Electric) the world company, said:-

"The effective pore sized the filter is gradually reduced as a number of the pores become blocked by build-up of smaller particles. These deformable particles are generally of the semi-solid nature and therefore are present in are a slime or gel like material. When the power of these particles is sufficient then an element may be "blinded off" which prevents flow. When these filters are washed they only retain approximately 10% of the total filtration value; the average our life is 2 months."

Possibly the GE principals are studying the worse case scenario, nevertheless it nevertheless clearly sports ths idea that Twelve months lifespan is unrealistic. Needless to say, many factors will play a part within how much time your spa & hot tub filters will 'last' - or maybe more importantly how long they shall be effective for.
