How Often Should You Wash Your Pillow?
The frequency of washing the pillow depends on several factors, including the type of pillow and personal hygiene practices.
Generally, washing pillows every 3 to 6 months is a good rule of thumb to follow.
However, if you sweat a lot during sleep or suffer from allergies, consider washing them every 3 months for optimal freshness.
Memory foam and latex pillows require less frequent washing compared to down or polyester pillows, which can absorb more allergens and moisture. Hence, adjust your washing schedule based on the different types of pillows and any specific health concerns you might have.
It’s also important to use protective pillow covers. They act as a barrier against dust mites and allergens, allowing you to extend the time between washes. Therefore, for the best results, opt to wash these covers monthly.
The Right Washing Methods for Different Pillow Types
Different types of pillows require specific washing methods to maintain their quality and longevity. Such as the following:
- Down and feather pillows should be washed with a mild detergent on a gentle cycle, and it’s crucial to rinse them thoroughly to remove all soap residues.
- Memory foam pillows are best cleaned by spot-cleaning any stains with a gentle mix of soap and water. Avoid soaking them, as excess moisture can damage the foam and cause it to deteriorate. For example: Shredded Foam Pillow.
- Polyester and synthetic pillows are typically more versatile and can be washed in a machine using warm water and a gentle cycle. Example: Gusseted Pillow.
Notes: Always read the care label for specific instructions related to your pillow type to avoid damage.
Can You Wash Pillows in the Washing Machine?
Of course, most of the pillows can be safely washed in the washing machine, which is a convenient option for maintaining cleanliness.
However, before proceeding, make sure to check the care label to ensure your pillows are machine washable and to determine the recommended water temperature and cycle.
For instance, when washing pillows in the machine, you can use a gentle detergent and consider adding an extra rinse cycle to remove all detergents thoroughly.
It’s advisable to wash two pillows at a time to maintain balance within the drum and prevent clumping.
After washing, squeeze out excess water gently before drying. Avoid wringing out pillows, as this can damage the filling and alter their shape.
How Else Can You Keep Pillows Fresh?
Besides regular washing, there are other ways to keep your pillows smelling fresh and clean. They are as follows:
- One effective method is to air them out weekly by placing them outside in direct sunlight. Sunlight acts as a natural disinfectant, killing bacteria and removing odors.
- Using pillow protectors made of breathable fabric can also help maintain freshness by preventing moisture buildup that leads to odors.
- Additionally, regularly vacuuming your pillows with a brush attachment helps remove surface dust and allergens.
- Sprinkling baking soda on your pillows and letting it sit for about 30 minutes before vacuuming is another great way to neutralize odors and keep them smelling fresh.
How Should You Dry Pillows?
Proper drying is crucial to prevent mold and mildew growth within your pillows. For example, air drying is a suitable method for most types, especially foam pillows that are sensitive to heat. Place them in a well-ventilated area and fluff them occasionally to help maintain their shape.

For machine-dryable pillows, use a low-heat setting and add clean tennis balls to the dryer. The balls will help fluff the filling and prevent clumping. Also, make sure, they are completely dry before use to prevent moisture-related issues.
Note: If you’re unsure about your pillow’s compatibility with a dryer, consult the care label or manufacturer’s instructions for guidance.
Can You Put Pillows in the Dryer?
In short, yes!
But it’s vital to do so cautiously. Here’s how to do it:
- Use the lowest heat setting to avoid damaging the filling and material. Consider using dryer balls or clean tennis balls to maintain fluffiness and distribute the filling evenly.
- Frequent checking is important to ensure the pillow doesn’t overheat or get damaged. Take pillows out periodically to fluff and reposition them, promoting even drying and maintaining their shape.
How Often Should Pillows Be Replaced?
Pillows should generally be replaced every 1 to 2 years to ensure optimal support and hygiene. Over time, pillows lose their structural integrity and may become a breeding ground for allergens.
Below are some of the clear signs that indicate it’s time to replace your pillow:
- If your pillow no longer bounces back after being folded, it’s a potential sign that it has lost its support. Similarly, if you wake up with neck or shoulder pain, it might be due to inadequate support.
- Persistent odors or discoloration on your pillow, even after washing, suggest that it’s time for a replacement. Over time, pillows accumulate sweat and oils that can lead to unpleasant smells.
- Lastly, if you notice allergy symptoms worsening, like sneezing or itchy eyes, your old pillow might be harboring allergens that require a fresh start with a new pillow.
