Reddit mentions of Culligan ISH-100 Inline Showerhead Filtration Attachment with Filter, 10,000 Gallon, White

I use this filter and replace the cartridge every 6 months. Makes a noticeable difference the water hardness.

One thing to consider if you are a gardener: I believe the cartridge uses salt to soften the water and that salt can be harmful to plants in the long term. So basically don't use these shower filters to soften water for the garden!

I'm going to go for overkill on this. Also this is using mostly natural stuff save for the facial lotion.

First - In the shower hopefully you have a strong stream that will strip the oil off of your face (Use warm water, but not hot). Keep in mind this is a terrible idea unless you follow step three. That oil is there to protect your face and keep your skin healthy. Please do not use soap on your face, just blast the water into it until it feels not oily at all. If your shower head is too weak then get a better one or get an Oil-Free acne wash. DO THIS EVERY SHOWER! - Always follow with step three.

Second, mild facial peel once or twice a week - Skip ahead or cringe through until you get to the part that matters. Might irritate a little the first two or so times, but this shit is magical. This will remove lots of older skin. I did this until things got relatively clear; now with Steps 1&3 I once in awhile throw in some St. Ives apricot scrub.

Step Three - Put some damn face lotion on your damn face. FACE LOTION; not any old damn lotion. I have had good results from Up&Up which I think is Target brand, maybe not. Also Jergens "Natural Glow" FACIAL LOTION has been good to me during the months that have no sun. After step three you have an incredibly clean protective layer of oil/lipids on your face. Both of these have an SPF; I suggest some SPF.

So what is going on here? Let me explain some theory, long winded style, because I think you will appreciate understanding what is going on here.

Alright; so I'm sure you know the general reason for blackhead formation. Shit gets clogged up in your pores (dirt, skin cells, etc) and this basically turns the oil in your pore solid; (Hold on I got an awesome metaphor coming up) once clogged your pore tries to push out more oil and then you get a problem.

Here's the metaphor.

Alright you have some water, throw some dirt in there.........you got mud. Throw some more dirt in there, well now you just have some damp dirt. Add more water you got mud, add more water and you wash away all the dirt. Oil and water are like enemies, they don't want to mix, but they react with everything else just about the same. So basically, you have some oil. Throw dirt in there, eventually it turns solid (blackhead), throw oil (lotion) on there before it turns solid and it'll stay clean. This is the basis for The oil cleansing method. The first time I tried this I was so damn amazed.

So, in the shower you wash as much dirt and oil away as possible, this also gets rid of bacteria and other stuff that sticks to your face throughout the day. Then when you do step two you remove future cloggers and bring fresh skin to the surface. Step three you rehydrate your face and give it a healthy amount of oil. This oil keeps your face from trying to shove out more oil from your pores in a natural attempt to rehydrate.

This really improved my face. Also a showerhead with a filter can also work wonders on skin in general. This is because often times shower/tap water has chlorine and other skin dehydrators/irritants in it. It'll also make your hair much softer to get rid of the chlorine. Also I don't use shampoo and my hair freaking rocks as opposed to the days I did use shampoo.

As far as nose blackheads. Many people's nose pores are fairly large. So they will hold a lot of oil in them. These aren't necessarily blackheads. The test would be to squeeze them out. If they worm out without a dark tip then they are not blackheads. Also a lot of guys don't know about blackhead removers (the things with a loop on both ends, the other end is for whiteheads. I freaking loved mine before I hardly ever had to break it out.

You can buy a water softener that you attach to your showerhead. I used this one for a while when I lived in an apartment with super hard water and noticed a difference.

My hair seems to be softer, and I can use whatever shower head I want.

I've got one of these on it. We get aquifer water here which has a ton of mineral deposits, so it's super hard. It doesn't work quite as well as a full water softening system, but the difference is certainly noticeable.

You can get an in-shower water softener that screws-on between your showerhead and the pipe coming out of your wall. The filters last ~6 months. It's fairly DIY item, and shouldn't violate any lease agreements (many people put their own showerheads on showers when they rent).

Here's one that I've heard is quite good for the price: http://www.amazon.com/Culligan-ISH-100-Inline-Shower-Filter/dp/B000MVYRWE/
