Did you know in the late 1980s, NASA did a study of common houseplants to see which varieties were best at purifying air inside space facilities? The study was a success and found very specific types of plants that cleaned the air of volatile organic compounds, or airborne chemicals. One of the plants is also one of the easiest to grow: aloe vera. Scientists found this succulent sucked up chemicals like formaldehyde and benzene. And one bonus benefit of aloe vera? The inner gel of the plant can help heal cuts and soothe burns.

When you’re buying a new mattress, don’t assume you have to invest in a matching box spring or foundation support in order for your new bed to work properly. Your old support is likely just fine in supporting your new bed. And if a salesperson suggests that not using the matching box spring will void the warranty, challenge them: Industry insiders say if you have problems with your mattress, they will honor your existing warranty. And while you’re at it, consider buying a bed frame that does not need a box spring. These are called platform-style beds, and they come with a built-in foundation support. They are modern, stylish and have a lower profile, too.

Adding mulch to your garden or landscaping is an easy way to help plants thrive, since it locks in moisture and blocks out weeds. But it can be expensive: about $11 for each eight-gallon bag. Instead, get mulch for free: Local parks and roads departments regularly haul away dead or fallen trees and grind them up into mulch. It’s free for the taking to use all over your home. If you’re worried the free mulch may also come with ground up weed seeds, simply seal the mulch in black garbage bags and let the sun’s rays exterminate the seeds. Spread the mulch and reuse the bags for garbage. Savings: Hundreds of dollars!
