In The Swim Premium 12 Mil

The In The Swim Premium solar pool cover is great for helping keep the heat in.


Thickness: 12-mil

Size: 12-foot

Reasons to buy


Good warranty

Reasons to avoid


No clear-colored option

The In The Swim Premium 12 Mil Solar Blanket is made of polyethylene and its thick material can raise the temperature of your pool by up to 15 degrees Fahrenheit. This can really help cut heating costs.

Raised air pockets on the surface of this thick blanket prevent your pool water from evaporating and protect it from things like falling tree branches or garbage - not to mention small, unwanted insect visitors. The air bubbles also trap heat and keep your pool warm. The thickness of this solar blanket means it’s pretty durable but the real winner is the impressive seven-year warranty to give you added peace of mind.

This solar pool cover also has UV-stabilized resin to prevent excess damage from the sun. If your pool isn’t round, that’s not an issue either as you can cut this pool cover to size.

While there aren’t many reviews for the In The Swim 12 Mil Solar Pool Blanket, it scores an average of 4.5 out of five stars on the company’s website. Users state that it effectively warms the water.

Sun2Solar 1200 Series Solar Pool Cover

This pool cover is great for a wide variety of swimming pools.


Thickness: 16-mil

Size: 16 x 32-foot

Reasons to buy


Great for in-ground and above-ground pools

Reasons to avoid



The Sun2Solar 1200 Series Solar Pool Cover is ideal for both in-ground and above-ground swimming pools. It's oval-shaped, however, you can cut it to suit your pool accordingly and this won't affect your warranty.

The small air pockets on the underside of the blanket capture and send solar heat back into the water of your pool, keeping it warm even on cloudy days. You can choose a blue or clear blanket, however, we'd recommend the clear version as sunlight can travel directly into the water.

It is, however, one of the most expensive solar pool covers that we’ve reviewed so there are cheaper alternatives available. In terms of user ratings, this Sun2Solar pool cover scores an average of 4.5 stars out of five on Amazon. Users that rate the solar pool cover highly comment on how they find it to be ‘strong enough that it won’t tear’. Others also found it to be durable and thick. Some users reported the bubbles began to come away after a couple of years of use.

Reasons to buy


Effectively warms up the water

Reasons to avoid



Featuring small bubbles that insulate your swimming pool, the Blue Wave NS120 is a solar pool blanket that can improve the temperature of your pool by up to 15 degrees Fahrenheit.

As a result of being left in direct sunlight, a solar pool cover must be made to be resistant to the wear and tear from UV radiation, along with the chemicals that you treat your pool water with. This is one of the pricier options in our round up, however, you do get a three-year warranty which provides peace of mind that your investment purchase will last.

This solar pool cover comes in a round design so won't be suitable for square pools, and it has been designed for above-ground swimming pools. It does, however, claim to prevent 'up to 95% of pool water and chemical evaporation'. So, you won't have to worry about spending time or money on replenishing it.

With an average rating of 3.7 out of five stars on Amazon, it's a solid choice. Users that loved the Blue Wave NS120 cover state that it 'raised the water temp over 20 degrees in a week'.

Intex Recreation 29025E

This solar cover is lightweight and easy to store.


Size: 18 ft

Reasons to buy


Includes carry bag for easy transportation


Easy to set up

Reasons to avoid


Sits on the water, rather than attaching to the pool frame

The Intex Recreation 29025E is a solar pool cover made from vinyl, making it a lightweight option that is easy to store, transport, and attach. It comes with a carry case, so you move it to a garage or storage area with minimal effort.

Air bubbles absorb and transfer sun heat into the pool water, resulting in a warmer water temperature that is much more pleasant to jump into. It reduces water evaporation by 95%, minimizing heat loss and how often you need to fill up the pool - better for your water bills and the environment. This cover will also keep debris out of your pool so less upkeep is required when it comes to cleaning.

It's 18ft and comes in a round design, making it a great choice for pools of the same shape and size. Reviews mention a downside being that it doesn't attach to the frame of the pool, inside just suctioning to the water itself, however there are no bad reviews mentioning that it lifts off or moves.

What to look for in a solar pool cover

The bare minimum your solar pool cover should do is keep your pool’s temperature from severely dropping by retaining the sun’s heat. Thickness and insulation are also essential so that there is less water evaporation occurring inside the pool. You also want a cover that’s going to keep the direct sunlight from draining the chemicals that are working to clean your pool, as you’ll have to top those up more if not, and run the risk of algae growing in their absence.

Safety should be another crucial concern when looking for a pool cover. Options that are easy to put on correctly will save you from accidentally leaving your pool unprotected, and importantly keep your pets and loved ones safe. Make sure that if your child or an animal were to step on top of your cover accidentally that it would be able to support their weight.

Thickness is the last factor to think about on your buying journey. Whilst a thicker cover will do a better job at retaining heat, these do tend to be more expensive, and more of a task to take on and off.
