The draft dried it out too fast, but have you checked the soil?

That soil looks bone dry and the leaves look like they're drying up. I think it needs a lot of water!

Soil seemed fine. I continue to water every 4 days but no results. I thought over water may have been the issue but you think it’s underwatered?

You need to have a soil moisture meter to see whether or not the soil is moist or dry. You could also use your finger, although for me that is a less sure way. My peace lilies like to be moist, but don't overwater. If you gave them a thorough watering, I don't think you would need to do it again in 4 days, unless they are in a very dry environment. I'm surprised it cam back as well as it did - it looked dead.

When you water, you should take that bottom saucer-thing off, put the plant in the sink and run water through until it comes out the bottom holes. Come back and do it again in 15 minutes. Let it drain thoroughly on a stack of newspaper for a few hours or overnight. It should perk up.

- Socks, do you think the faucet water is fine for the plant?

When some potting soils dry out they won't absorb water readily, it just goes down the side of the pot and out the bottom. It's best to sit the whole pot in water for a while and then let it drain out.

Most water authorities use chloramine these days as it's more stable and won't dissipate. Leaving it out over night doesn't help. It's good it you can find out what they do put in the water so you can work around it.

How long have you had this plant, and did you repot it? if so, when? It just looks bone dry in your photos! And why do you water every four days and how much water do you give it?

I have to agree...looks REALLY dry. I've seen mine get almost this droopy, but they typically bounce back with a thorough soaking.

On the moisture meter - they certainly work and are a cool thing to use, but, quite honestly, I gave up on them years ago and wouldn't say that it's an essential item to have in order to be successful growing houseplants. Generally the once-a-week method (for most plants) seems to have served me well over the years. If a plant has been newly transplanted, however, then it can often go quite a bit longer.

From what I have learned on this forum moisture meters are not accurate! Using a ”tell” is a better way. Use a wooden dowel sharpened, stick it n the pot to the bottom and if It comes out dry then water throughly til water comes out the drain hole. Find Al Tapla’s thread on watering practices for container plants, it is better explained there.
