Water Resistant: Filter cover Hydrophobic treatment helps repel moisture and protect against water entering the engine due to puddle splash or heavy rainstorms. Although our Pre-Filters are proven to be extremely effective in repelling water, please keep in mind they are NOT WATER PROOF. If submerged, your intake can hold or pass water. This treatment will last for six months to one year, depending on use and conditions. As a general guideline we recommend replacing your Outerwears air filter cover with every other air filter service to help maintain its intended performance benefits. A quick test can help determine if it is time to change your Pre-Filter. Simply take an ordinary clean spray bottle filled with water and gently spray the Pre-Filter. If water beads off the Pre-Filter, your water repellency is still working. If you see water enter through the Pre-Filter, it is time to purchase a new cover. - - Maintenance & Cleaning - Depending on driving conditions, service intervals may vary. We recommend making a visual inspection as often as you would normally service your vehicle. If your vehicle sees a lot of dirt track competition (pulling/dirt drags) or dirt road driving, we recommend viewing the Pre-Filter at least after every race or trip. If you see a significant amount of dirt, you should clean the Pre-Filter. If the only driving you experience is street, we recommend checking the Pre-Filter every 3,000-5,000 miles. Although your Pre-filter may not require a thorough cleaning, you may want to shake off excess dirt to maintain your optimum horsepower and fuel efficiency, then reinstall. Caked debris can be loosened by soaking this filter cover, after being removed from your main filter and vehicle, in a mild soapy water solution and then rinsed clean and allowed to dry before re-installation. Do not scrub or use aggressive cleaning chemicals as the pre-filter and hydrophobic treatment can become damaged resulting in reduced efficiency and premature failure.

Foam Mattress NEEDs Foam Pillows
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
10 stars!! Quality foam, structure & price. Best bang for my buck.    HRV, readiness & total sleep score metrics increased drastically this week.  See screenshot :) Support: Molds and cushions every crevice under my neck and above shoulders. So comfy  Size: Adjustable loft but king length is perfect to hug and rest your head.  Love love love. The 1st 2 nights were uncomfortable with pillow as is, first night I was up at 3am half asleep pulling foam out but wasn't enough. The second night at 2am I pulled out more stuffing. I was getting frustrated..  my Oura ring showed both nights I was awake every hour.  Not good.  Before the 3rd night I pulled enough to fill the bag the 2 pillows arrived in. Boom -8hrs sleep and for the first time ii years I achieved 17% Deep sleep.  Huge. Weight: Perfect weight with adjustment. Squishy and molds to b the contour of my neck and shoulders Softness: Like the baby bear.. just right.   Comfort: Very comfortable after removing 30% foam in both pillows. I actually now have enough to make a 3rd pillow, replace old foam, or adjust OGs, Still to early to measure.  If you have a foam mattress that contours your body but not your head you'll end up with neck and/or back pain from head being elevated- not sinking/molding the body into a foam mattress.

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back. I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size. pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King. I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem. A shame, would have given them a great review if they were the correct size

Really Good Cooling Pillows for Sleeping
Color: Blue-ice Plus, Size: Queen(Pack of 2), Color: Blue-ice Plus, Size: Queen(Pack of 2)
These cooling pillows are very soft and provide excellent support for your head and neck. They are adjustable by taking our the stuffing if you need them to be more flat or less firm. The look great and comes in a pack of two which is a great value. During use, I did notice they have great shape retention and it does not take them long to return to their fluffy full shape. I am a hot sleeper and these do keep your head cool - just be aware using a pillow cover does reduce the cool ability but this allows you to adjust for weather like during winters to add a pillow case for extra warmth. Very happy with this purchase and got a second set to replace my old pillows.
