I was thinking I would start looking into purchasing a reverse osmosis unit shortly. I have a few questions for those of you who know more than I do about them. I have looked online and found units that have very few stages to 6 stages. Prices anywhere from $70 to a lot more.
1. How many stages do you recommend?
2. Any particular brand you recommend?
3. Where did you/would you purchase from? ebay?
4. How much should I spend to buy a unit that would suit my needs? (1-2 gallons a day to water/mist nepenthes)
Any insights you could give me would be much appreciated. Thanks.
