Should I use a mesh or solid pool cover?
This is probably the most common question we get. The primary issue in most cases is safety. If there are small children or animals involved, always use an ASTM compliant safety mesh cover.
A safety mesh cover will not allow water to aggregate on top of the cover, and therefore virtually excludes the possibility of accidental drowning. A safety mesh cover will not stop very fine dirt particles from filtering through during rain or snow, so you may do a little extra clean-up in spring. That is a very small tradeoff when it comes to a child's safety. Mesh covers are also less expensive than a solid cover.
A solid cover can stop nearly all particles from entering the pool. However, even with a pump or mesh drain panel, solid covers can allow significant water collection on top of the cover and can become slippery from normal particle build-up and moisture. This is one reason we strongly recommend mesh for households where unsupervised child access is possible. A solid cover can be used when there is no possibility of a child getting near the pool in an unsupervised situation.
