Towels

Replacing towels can be tricky, but in general,most towels lastfor approximately two years.

However, there are exceptions to this rule.

Conversely, towels used to dry your hands multiple times a day may only last for one year.

Repurpose old bath towels for home cleaning or donate them to a local animal shelter.

Check the manufacturer’s recommendation, always.

When you install a new one write the date of installation on it.

If your home was recently renovated, you may also want to get rid of your old smoke detectors.

Dust, cobwebs, and other air pollutants can contaminate the internal sensors.

Its not a lot of money invested to preserve your life, says Christie.

According to a bedding expert fromCozy Earth, you should replace your pillows every one to two years.

Pillows can contain allergens like dust mites and pet dander.

It can also lead to allergic reactions, breakouts, and neck pain.

Replacing them regularly helps ensure your pillows are clean, free of allergens, and supportive.

Mattresses

There are very few things more disgusting than an old mattress.

So when should you replace yours?

Jack DellAccio, founder ofEssentia Organic Mattresstells me it varies.

The denser the foam of a mattress, the more durable or supportive the mattress will be and remain.

Cookware

Cast iron and metal cookware can last for many years.

However,non-stick panshave a limited lifespan.

If a non-stick pan is scratched, peeling, or discolored, it should be thrown out.

Toothbrushes

Oral hygiene is important to your overall health.

So you dont want to use a toothbrush thats germy or no longer capable of cleaning your teeth.

According to theAmerican Dental Association, you should replace your toothbrush every three to four months.

However, if youre a hard brusher or the bristles are looking worn, you should replace it sooner.

Bedding

The good news is thatbeddingdoesnt have an expiration date in terms of safety or comfort.

However, once bedding starts to look worn, its probably time to shop for something new.

So, new bedding is more important than you might think.
