Best Praise
+6 ptsโYou say it's not practical to buy distilled but you invested all that money in filters and air purifiers but don't want to spend any money on water. I see this constantly where people are talking about White mineral dust settling on everything, Dirty hard to clean humidifiers with orange crap in the bottom, Coughing etc. The simple solution is to use Distilled water. I have a Levoit 450S in my bedroom that has a 4.5 liter tank that lasts about 3 days plus I use a CPAP. So I go through about 5 gallons per week which is around $1.50 a gallon at Walmart for the Great Value one which comes to about $7.50 a week which works out to about $30.00 a month. A small price to pay for not having a nasty clean up problem with the humidifier. I don't see any nasty stuff in mine and once a week I empty it and soak the parts in a solution of half white vinegar and half water. So far I haven't seen any nasty stuff in my humidifier at all, it's spotless. No White Dust or coughing either. So yes distilled water cost money but it's a small price to pay for the benefits you get from it.โ
