What should I keep in mind when buying a home water maker?1. Run a cost analysis Prices for a water maker are in the $1,000-$1,500 range. Factor in also the amount you'll be spending on electricity and you'll quickly see why you'll want to calculate the cost effectiveness of a machine before you purchase. The numbers can be surprising. For example, the DewPoint runs about $1,600, but only uses about 330W, and claims a cost breakdown of about $.60 per gallon, whereas the EcoloBlue 28 runs about $1,400 but uses 1000-1150 W for water generation, yet claims a cost breakdown of $.20 per gallon.
DewPointe gives a cost breakdown of various water sources:
Home Bottled-Water Delivery $1.50 gal
Food Store (grocery) $.90 gal
Water Store $.50 gal
Vending Machines $.35 gal
Private Label Bottled Water $2.24 gal
Standard Bottled Water $3.16 - $5.28 gal
Premium Bottled Water $5.50 - $10.80 gal
DewPointe™ Atmospheric Water $.60 gal
You'll want to rfind out the cost per gallon on the models you're considering, and double check their accuracy, before making a decision.
2. Asses atmospheric conditions in your home
Is where you live a good place for a water maker? If you live in a place with low humidity, high altitude, or other factors that make collecting water from the air difficult, you might find that you're using up a lot of electricity for hardly any water. Assess your environment before making a purchase.
3. Do you really need one, or would a water filtration system be better until the technology improves?
There are some locations where a device like this makes a lot of sense - the atmospheric conditions are ideal and other fresh water sources are less than ideal. However, you'll want to carefully weigh the pros and cons before buying one of these machines to have on hand in case something happens to your water supply. For the most part, finding a good water filtration system might be the better route to go.
