It must be remembered that the most important aspect of a pool's appearance is 
the quality of its water. The key to this is efficient filtration and a pool's filter is the 
one piece of equipment where compromise does not pay. DAYLIFF 'DX' filters 
are quality products which have been carefully designed to combine the highest 
standards of performance with outstanding reliability and ease of operation. 
With a DAYLIFF filter clean, sparkling water is assured at all times.
