Here's another picture...

When I had a screen porch, I used matchstick blinds. They would block dirt and pollen a bit, but they would also get dirty. And the screens would be dirty, regardless. My porch had a stone floor and block half-walls. In late spring I'd just hose it down because it was so dirty after a long winter and pollen-filled spring (Virginia). But your windows are so pretty and arched, I don't know that I would want to cover them up with blinds. Can you see the porch during seasons when it is not in use? Maybe you could have arch inserts made with a translucent/transparent covering that would block most everything.

Thanks, andee...good thinking about the arches. My hubby agrees! You cannot see it from my kitchen...we walk down a small hallway to get to it...

Arch inserts, eh? I will have to google that...I'm stumped as to how to cover them.

Smart that u had a stone floor - I wish we would have chosen that!

If my daughter didn't have allergies I might not care as much. The thought of lounging on furniture out there that has a coat of thick pollen on it...and then coming inside...just isn't an option! Maybe if I didn't clean my own house...;). But alas...no housekeeper here;)

Here's another view...add two more windows to this pic and there u have it! No furniture yet - I'm looking at a resin wicker set from crate and barrel...but want to figure out the windows first...

I live in Western PA and also have a screened in porch and wicker resin furniture. I cover the furniture (biggest pieces) throughout the winter. I have found if I wait til late May to do the major cleanup, most of my pollen season is over. Do you have pollen issues all summer long?

It's a porch. It's going to get dusty and dirty and covered with pollen.

In your situation, I'd consider making this a 3-season room, as they are called in my area, and cover the arches with windows that you can open. That's the best way to control the dust and pollen.

If you don't want to do that, then I'd get furniture that you can easily clean with a hose. And maybe keep the cushions indoors unless you are actually sitting out on the porch. The covers ratherbesewing would also help.

I just think if you try to keep the porch pollen-free you are going to spend all your time doing that, and very little sitting down and enjoying the porch.

You could also have removable storm windows made for the arches. They would add some insulating value during the winter, and you could leave them up until pollen season passes. They would completely block dust and pollen while they were up.

Looking at the arches a second time, is there space for shutters either on the inside or the outside of the porch? If you get good ones, they might keep out the pollen and dust, but could be easily opened when you want to use the porch. And they'd look appropriate in an outdoor setting.

We live in coastal SC and the pollen is REALLY thick in the spring. We have resin wicker furniture and keep the cushions in a big deck box. When it is pollen season, sometimes we cover the furniture with inexpensive flat sheets. We have glass topped tables, and the cats tend to lounge on them, then come back in the house with their fur covered in pollen! I don't think you will find a shade nor any type of window covering that will keep the pollen out.
