6pk 21x23x1 MERV-11 Air Furnace FiltersLet's take a moment to talk about your furnace filters. You know you need to swap them out more frequently than you change swap out your standard air purifier filters. That's because there's a lot more air that gets pushed through these filters. With this increased amount of air comes a larger amount of debris. Thankfully, these filters are rated MERV 11, which means they're some of the best residential filters available. Just make sure to inspect

    Compact & soft cap
    Color: Dark Navy, Size: One Size
    Great fall/winter hat if you’re looking for something that’s not too bulky. I wanted for a winter hat that I could just keep in my inside pocket of my winter jacket - problem was the pocket was not very big. I had another knit cap that just did not fit in there. The Danish Endurance beanie fits the bill! Being so thin, it is not my warmest beanie – but gets the job done! It also feels so soft. I bought another in a different color! The hat arrived with a few creases in it. You could steam it, but don’t really notice any wrinkles when you put it on. I wish they made it in a darker gray/charcoal.

    Soft but flimsy
    Color: Dark Navy, Size: One Size
    Its soft and warmth is ok, but it feels very thin and a bit flimsy. The knit at the top looks particulary fragile. I think for the price this is still ok value but I do not expected it to last a long time.

    Cashmere but far too thin
    Color: Dark Navy, Size: One Size, Color: Dark Navy, Size: One Size
    The beanie feels soft and genuinely made of cashmere, but the fabric is surprisingly thin — almost transparent when held to the light. It lacks the warmth and structure you’d normally expect from a cashmere item. The design and packaging are pleasant, but the overall impression is disappointing. It’s comfortable to touch yet too delicate to provide real protection against the cold.

    Cool hat.
    Color: Dark Navy, Size: One Size
    This is a nice little hat. Even though it’s really thin, it does seem to keep my head warm. Really haven’t tried it out in the wind yet. But saying that you could put another hat on top of it.
