As per the National Sleep Foundation, change pillows after every 2 years. The same goes with the bamboo pillows also. No doubt it may last longer like 4 or 5 years easily but it will be good if you replace it after a couple of years.

Pillows are one of the few things that we can't have on a long-term basis. Your pillows will eventually get too old to be used, and when this happens, it isn't worth keeping it. While some pillows are more durable than others, all pillow experience wear and tear.

Using a new pillow can be traumatic, especially when you just bought it. Replacing your old pillow with a new one can make an enormous difference in your sleep quality. You need to find a new pillow that won’t disintegrate from the weight of your head or neck and add support to your cervical spine.

Why there is a need to replace your old pillows?

We ask you to remove the pillow from your bed and replace it with a fresh one when we clean your room. When you're done sleeping on your pillow, we'll collect it so that no one else shares your germs. After putting your head on your pillow, you leave behind some pretty grisly stuff – sweat, skin cells, oils, dust, dust mites, drool, makeup and other facial products, hair, all kinds of allergens, and more.

Your pillow does the dirty work. Yes, you can toss your best washable pillow in the washing machine with your sheets and linens, but you won't be able to prevent some of the unwanted materials from sticking around. That explains the stains. When you sleep, dirt, germs and dust might be breathed in. Sleeping on a dirty pillow can irritate the skin and cause acne. So, regularly replacing your pillow can mean you’ll get a healthier night’s sleep every night, rather than breathing in dirt and germs.

Allergens

We all lose skin every day, which is one of the many ways in which dust mites thrive. The Asthma and Allergy Foundation of America estimates that dust mites might be responsible for up to 70% of treatments given to people with allergies and asthma. If you wash your pillows regularly, it may still be difficult to remove allergens.

You sleep on your pillow and your mattress, so those are the key pieces to support your neck, head, and spine. Your pillow will eventually flatten out and stop offering proper support. A new pillow offers the greatest level of support and comfort.

Buy a high-quality pillowcase and a quality pillow cover. Make sure you wash the pillow often to maintain its looks. Pillow covers and cases will also last as long as they are good quality.
