What can I use if I don't have distilled water?
An alternative to distilled water is mineral water. The process of distilling is simple. Heat tap water to the point that it turns to vapor. When the vapor condenses back to water, it leaves behind any mineral residue.
CPAP manufacturers recommend distilled water for optimal humidifier performance. This is because most or all of its minerals have been removed, preventing mineral buildup in the humidifier tub. However, tap or bottled water may also be used.
No, boiled water is not the same as distilled water. Boiling your water may kill any microbes, but it won't remove chemical or mineral contaminants.
STEP 4: Boil the water and monitor the ice left in the lid.
If the ice in the lid has melted, dump it out in the sink and replace it with fresh ice (use oven mitts; the lid will be hot). It will likely take about 45 minutes or so to turn the tap water in the pot into distilled water.
Once the water entirely vaporizes, that vapor is put into a clean container where it condenses back into pure water. So merely boiling the water will not distill it, it will only potentially remove few toxins.
Leave the container outside for 2 full days to allow the minerals to dissipate. Store the distilled water in clean jugs. Note: While this method can produce drinkable water, it's possible for pollutants and harmful bacteria to remain in the water.
You can use bottled water in your CPAP humidifier if it is distilled water. Most bottled water used for drinking is purified or spring water. These don't contain bacteria, but they may have minerals like calcium and magnesium that can leave residue in your humidifier and may cause it to wear out quicker than expected.
Distilled water is the recommended choice by CPAP manufacturers to extend the life of your CPAP machine and prevent mineral buildup. If the CPAP machine gathers mineral buildup, it can prevent the humidifier's heating plate from properly warming the water.
Boiling water kills microbes but does not remove minerals or chemical contaminants. You may actually get more mineral buildup in your CPAP because the minerals become slightly more concentrated as the water evaporates when it's boiled.
Distilled water is sold out because of a combination of record high demand, shortages and supply chain slow down.
Can bacteria grow in distilled water?
Many microorganisms ("oligotrophs") grow in distilled water: Pseudomonas spp., Caulobacter spp., Hyphomicrobium spp., Arthrobacter spp., Seliberia spp., Bactoderma alba, Corynebacterium spp., Amycolata (Nocardia) autotrophica, Mycobacterium spp., yeasts, and Chlorella spp.
As physician Nina Radcliffe explains in The Press of Atlantic City, microwaving water or other liquids past the point recommended by manufacturers could result in serious burns because it becomes "superheated" which she describes as "water heated beyond its boiling temperature that does not have signs of boiling — it's ...

Tap water contains mineral deposits, microbes, and germs that you don't want to risk breathing in. Overtime, these contaminants can also build up on your supplies and damage your CPAP tubing and motor. Distilled water should be the only water placed in the water chamber for use.
Usually, the label will say something like, “minerals added for taste.” You should only use genuine distilled water with no minerals in your CPAP machine.
Distilled water is recommended in your humidifier tub.
Can you use a CPAP without the humidifier or water chamber? CPAP machines are usable without a humidifier or water chamber. The machine will continue to disperse dry air to your mask.
Distilled water for babies is the same as baby water except for added minerals. After baby water is purified, a few trace minerals are added for taste. So, baby water contains a small amount of magnesium, potassium, and calcium. Distilled water does not.
The water quality report states the pH of Great Value Distilled Water is 5.7 and the TDS is ND (none detected). Walmart does an excellent job of making this report easy to find and they are very transparent. Other stores make it extremely difficult to find.

NEW JERSEY - Distilled water is an important type of water for millions of medical devices in the United States but some users are having problems finding it. Along with in-home uses, it is also used in dental and medical offices to help sterilize equipment.
Is it cheaper to make your own distilled water?
Distilled water is a more specialized type of purified water, but much easier and cheaper to produce at home.
Bottled water usually undergoes filtration processes rather than distillation because it contains essential minerals that affect the taste and nutritional value of the water. Distilled water, on the other hand, is entirely pure H20 because distillation removes all of its impurities, including minerals.
Distilled water is sold out because of a combination of record high demand, shortages and supply chain slow down.
5-gallon bottles are perfect for traditional distilled water uses.
How long does it take to distill water? It takes around 4-6 hours for a countertop water distiller to produce one gallon of distilled water. Like most high purity water filtration methods, the process of water distillation is a slow one. The water distiller produces purified water one droplet at a time.
