Product image shown is a representation only. Actual products may vary in appearance, size, or other.

HYDROSCIENTIFIC™ SPX SERIES POLYESTER PLEATED CARTRIDGES are manufactured from durable polyester to provide a superior pleated, washable, reusable cartridge. The Polyester media is pleated around a Polypropylene core for added strength, and the ends are immersed in a thermosetting Vinyl Plastisol, which fuses the three components together, forming a unified end cap and gasket. The cartridges are bacteria and chemical-resistant and provide great dirt-holding capacity to extend the time between cartridge changeouts.

HYDROSCIENTIFIC™ SPX SERIES POLYESTER PLEATED CARTRIDGES are made with 100% pure polypropylene and are free of surfactants, detergents, and anti-static agents. SPX series filter cartridges do not impart any substances into water that are known to or can cause adverse health effects to humans.

These are very thick pillows.
Item Package Quantity: 2, Size: Queen
Exactly as advertised. They are very firm and very thick. They're too thick for me to be able to use as bed pillows. However, they seem to work pretty well as cushions in my papasan chair on top of its normal cushion also work very well as decorative pillows. I'm still giving them four stars because they're exactly as advertised and they seem well made. My only complaint is that they're just too thick. And that's definitely not the fault of the pillows or the pillow maker.

how good the product is
These pillows are soft, fluffy, and surprisingly supportive for the price. They’re comfortable no matter how you sleep — whether on your side, back, or stomach — and they maintain their shape well overnight without going flat. The fabric cover feels smooth and breathable, keeping things cool through the night. After a few days of fluffing and use, they settle nicely into a perfect medium firmness. They also wash and dry easily without clumping. Overall, a great‑value pillow set that offers comfort, versatility, and quality — ideal if you need an affordable yet cozy bedding refresh.

Firm and comfortable
These pillows are well made. Firm, yet comfortable. I am pretty rough with my pillows. I toss and turn frequently. After one year, they are still holding up.

Quite good. I am actually surprised. Too small for queensize
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.
