Why Should I Purify My Water?

Water purification can help ensure the water running from your taps is healthy and clean, reducing the harsh effects of harmful water on your appliances and improving your overall life.

You may choose to purify your water to help:

  • Improve the purity of your water and reduce residue
  • Reduce your consumption of plastic bottles—drink straight from the tap
  • Improve your skin and digestion by reducing harmful chemicals
  • Get clean water without adding more chemicals

Types of Water Purification

Cross Heating & Air Conditioning is committed to providing you with several water purification options. These different types are made to suit your lifestyle and home needs.

The technicians and comfort advisors are here to answer any questions you may have and help you find the solution that works best for you.

Reverse Osmosis

Using a reverse osmosis water system only allows pure water to leave your taps. Reverse osmosis works by passing the water through an efficient membrane, reducing impurities and providing you with the best possible—and best tasting—water.

Ultraviolet Sterilization

Ultraviolet (UV) sterilization occurs where the water enters your home and is an increasingly popular method of water purification for people who have wells as their water source. The water is sterilized at the point of entry, ensuring an environmentally friendly, chemical-free, and low-maintenance way of purifying your water before it enters your home.

Point-of-Use Filter

An inexpensive way to purify the water coming out of your taps is to use a point-of-use filter. These types of filters attach onto individual taps to help reduce sediment and the odour of your water while improving taste. This type of water purification is useful if you don’t have many taps used for drinking or bathing.
