If you've in the market for a toilet, you're probably weighing your options for optimal performance and eco-friendliness. Dual-flush toilets were a great option for a while, since they used far less water for liquid waste, but the newest high-efficiency toilets are using a gallon or less of water per flush, every flush.

Foremost Group's Power Assist Two-Piece High Efficiency Toilets use just 1 gallon per flush, while Niagara Conservation's Stealth toilet uses a mere 0.8 gallons per flush.

So how do they work?

The Stealth has a larger water spot (opening), allowing waste to be flushed away more easily. The system uses water and air to force waste down and refill the bowl. What's nice about the design is it functions well even with changes in water pressure, which happens in a lot of older areas.

The Power Assist uses a powerful but quiet compressed air system to force the waste through the pipes--similar to the systems used on airplanes and on trains. And the toilet is able to flush twice the weight of the average solid waste.

What does this mean for you? For a family of four with each person flushing the toilet five times daily, it means up to 20,000 gallons in water savings yearly over a standard toilet, which will save you about $100 each year. If you have a high efficiency toilet that uses 1.6 gallons per flush, a family of four will still save more than 6,000 gallons of water each year with the Stealth, or about 5,000 gallons with Foremost Group's toilet.

So whether you're remodeling or you're just looking to upgrade to a more efficient toilet, the newest one-gallon-or-less per flush toilets are the way to go.
