Start with maintaining at least 35% humidity level in your home.

Really nice room. Looks comfortable and inviting. Good choice w/new sofas. Like the fireplace as is ... but less clutter could improve the look of it. Not sure what the picture is above the piano. If it is a family photograph, reframe it and the family photo on the mantel with the same frames and put both above the piano. Really like your coffee table. One day it will be a valuable antique if you don't booger it up. So, for the coffee table, consider taking the table to a glass company and having a dark gray tinted thick glass top created for it -- no refinish for the table necessary. (Alternately, cover everything but the top and paint the top only -- perhaps black or else the same white as your cabinets.) Do the same for your current end table as you do for the coffee table. If you're going to add a second end table, since matching the existing one would likely prove difficult, consider a totally different look -- perhaps a wood 2-drawer filing cabinet? http://realsolidoak.com/office.html

Lovely space and a lot of great choices already. If you’re willing to switch out the dark brown dresser, would you consider painting it? Maybe a pale blue chalk paint if you’re bring in a few blue/teal/green accents? On the other hand, if you lighten up some of the pieces in your vignette, keeping it the way it is could still work. Find a selection of clear green and turquoise bottles to replace the black ones in your vignette. The lamp is a little too far to the right, the tray with bottles needs to move a smidge to the left. Try covering the books in white to repeat the white from other pieces in the room. I’m an allergy sufferer myself, so I completely get the no rug thing. And all throws and pillow covers must be washable, etc. Regarding plants and dust... very easy solution for that is to give your plants a shower every so often. This works incredibly well to keep them watered, dust and insect free, and is really easy to do. I use cool water (not completely cold) and don‘t turn the water on full blast so that it’s fairly gentle on the plants. Leave it in there for a bit to drain, and then they can go back to their normal spot.

I think you have some very pretty spaces here and have already done a more than respectable job with the decor. For the living room in particular, it only needs tweaks, such as raise up the art higher (and pull that sofa a bit from the wall, so that no one feels nervous about hitting their head on the art); take everything off the media unit that has height and make the decorations low bowls or trays. Plants look wonderful in that room, so bring in as many as you can handle. Are you completely averse to a light toned shag-type rug for your living space? if that doesn’t work for you, a sisal is fine. That rocking chair in the corner of the dining room isn’t going to get used, so I’d replace it with a plant. In the other corner, instead of sticks, get a free standing or wall mounted wine rack. For the dining chairs, I would go for ones in colourful or transparent plastic (these come in different colors) or if you prefer the comfort of upholstered go for bright colors, florals or graphics, or solids. Coral, aqua, — whatever you like. You could have a livelier linear light fixture, either something curvy or feathery or with shine. What you have is fine with your chairs, but after you switch out the chairs, maybe you’ll want a new fixture. I love your glam Monroe headshots in the kitchen. A more fun and flashy kitchen clock would be nice, as would pop-style utensil holders, fruit bows, dishtowels, fab dishwashing gloves and a great cooking apron or 2 I would make bar stools the last purchase. My problem with macrame is that it collects dust. If you like fabric arts (and they can be inexpensive and easy to hang) look at batik wall hangings and Japanese noren curtains — that kind of folk art, which can have bright colors or subtle designs.
