Certain household products can save you a substantial amount of money over time. If you want to lower your household spending, consider getting these four items.

An AeroPress Espresso and Coffee Maker

Buying a single shot of espresso at Starbucks costs $1.75. Your daily caffeine habit could easily cost over $12 per week, and that doesn’t even include the tip for your barista.

Purchasing an AeroPress on Amazon.com will cost you $33.90. The kit includes 350 filters, so you will have enough for nearly a year of delicious coffee drinks.

While you still have to buy coffee to make espresso at home, the cost pales in comparison to that of buying drinks at a cafe. You’ll make your money back in a matter of months.

Niagara Earth Massage Low-Flow Shower Head

The Niagara Earth Massage Low-Flow Shower Head costs a mere $8.00 and uses 30% less water and energy than a regular shower head. You not only save money by conserving water, but by using your water heater less.

At such a low cost, it won’t take you long to make your money back when you purchase the Niagara product. The specific amount of time depends on how many people there are in your family and how long you like to stay in the shower. Regardless, you’ll lower your water and energy bills while helping the environment.

Nest Thermostat

The most recent version of the Nest thermostat isn’t cheap. It costs about $243. But consider it an investment–the thermostat gives you considerable control over your home’s comfort and how much money you spend on electricity and natural gas.

Nest learns your daily habits so it can adjust your home’s temperature throughout the day. Just before you get up in the morning, it will change the temperature to keep you comfortable. When you leave for work, it will tell your HVAC system to work less. This conserves energy until you’re scheduled to come home, when Nest turns the heat or air conditioner on, again.

Although it may take you a couple of years to break even from the purchase, you’ll eventually see an impressive return on your investment.

Lasko Ceramic Heater

Sometimes you only need to heat a small area rather than the entire house. If you want to heat just a bedroom or living room, consider purchasing the Lasko Ceramic Heater to see big energy savings.

Laski’s 754200 Ceramic Heater costs just $27.29. It comes with a three-year warranty and has a quiet setting so it won’t interfere with your sleep.

By buying just a few key products and adjusting your habits, you’ll be amazed at how much you can save over time. With these four products, you’ll reap the rewards for years to come.
