A Smarter Safety Cover: For years pool professionals have been looking for a safety cover that fulfills all of their customer's needs. Wouldn't it be great if there was a cover that combined all the pros of mesh and solid covers and eliminated all the cons? Merlin is proud to offer SmartMesh. A patented mesh safety cover whose time has clearly come! It's like putting a filter over your pool!Only from Merlin: Developed by the Merlin R&D team and a leading material manufacturer, SmartMesh is not just another mesh cover. This revolutionary product will give you an edge over your competition. Offer your customers something different, something that works. Once again, Merlin Industries listens to the feedback of our dealers and their customers and produces an innovative and patented product to meet their needs.

Some of the Specs:
  • 100% Shade, not 99%, not 98%, not 97%, not 95%, 100% shade minimizes algae risk.
  • SmartMesh is 40% lighter than solid cover material.
  • Average filtration down to 40 microns. (Sand filters typically filter to 20-30 microns)
Until now pools with mesh covers have had a tendency to open up looking more like a frog pond than a pool! Each season, pool owners pull off their mesh covers and go to work trying to get their pools clean and clear enough to swim in. Sometimes this process can take weeks and cost hundreds of dollars.

That is why we developed SmartMesh. A truly unique mesh material, SmartMesh provides 100% shade from the algae causing rays of the sun, while still allowing rain and melting snow to pass through the cover material. This material is so special we were granted a U.S. Patent!

100% shade is not all SmartMesh provides you. SmartMesh filters debris as small as 40 microns. To give you a comparison, a typical sand filter for a pool filters debris as small as 20 to 30 microns. SmartMesh is like having a filter over your pool!

SmartMesh is also much lighter than a solid safety cover. Approximately 40% lighter! SmartMesh is easy to put on and take off.

SmartMesh is the ultimate in convenience and function when it comes to safety covers. It is no wonder all of our competitors are trying to copy this one of a kind cover material. Make sure your cover says Merlin. Make sure you get Patented SmartMesh. Look for our U.S. Patent number on the brochures and web-sites of our competition. You will probably see our patent number and the shade percentage their material provides. No other safety cover on the market provides 100% shade. Don't settle for anything less!

What is a Safety Cover? A safety cover is a woven mesh or solid vinyl winter cover that can be used on in-ground and above-ground swimming pools. The safety cover is designed to be pulled taut across the swimming pool and secured with straps to anchors that are installed around the perimeter of your swimming pool. Safety covers not only protect your swimming pool water from leaves and debris but also from accidental drowning.

What is the difference between Mesh and Solid Safety Covers? Mesh Safety Covers: The mesh material is generally lighter and easier to handle than solid material, which means you will have an easier time installing or removing the safety cover from your swimming pool. The mesh material also allows rain water and melting snow to drain through the cover into the swimming pool.

Solid Safety Covers: The solid material comes with the advantage of preventing all sunlight and fine particles from entering the swimming pool. This helps to keep your swimming pool water cleaner during winter by preventing dirt and algae accumulation. Because the cover is made from a solid material, a mesh drain panel or a cover pump is needed to drain rain water and melting snow from its surface.

Why should I buy a Safety Cover for my swimming pool?
  • Protects your investment during the off-season
  • Safeguards your family and pets from accidental drowning
  • Saves time and effort when opening and closing your pool
  • Saves money in the long run
  • Gives a more customized and finished look to your swimming pool
Important Safety Cover Notice: You will need at least 3 feet of concrete all around your pool to accommodate the installation of this safety cover. Customizing a cover to fit any size pool through PoolSupplyWorld can be a very economic option and will ensure a perfect fit. We caution you against trying to save money by purchasing a rectangle cover to fit your free-form pool or 4 foot rounded radius corner pool as the covers will probably not fit well and will cost you time and money in the long run. If your pool has 2 feet or less of radius rounded corners, the rectangle cover will work; if you have more than this, please contact us to let us help you purchase the right safety pool cover for you. If you purchase a safety cover that is not the correct size for your pool, your warranty will most likely be voided. We are here to help, please contact us at 800-772-0467.

Why would I need a Custom Cover? Why won't this stock cover work for our pool?
  • If your pool is not a perfect rectangle and/or has rounded edges of more than 2 feet in radius
  • If your pool does not have 3 feet of concrete around the entire perimeter of the pool
  • If there are objects around the pool like diving boards, un-removable ladders, slide legs, and water features
  • If you cannot find your correct size online
If any of the above applies to you, we recommend a custom cover for your pool. Contact us at 800-772-0467 and one of our knowledgeable sales associates will be happy to assist you.
