For a half-mask respirator, I like this 3m model that has a quick latch: https://www.amazon.com/gp/product/B00IF7RBS4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
The Trend air shield is good for dusts in that it is constantly blowing filtered air over your face. No inhale/exhale valves to worry about, and would be the preferred type if you have any breathing difficulties (COPD, Asthma, etc) or lots of facial hair that prevents a conventional respirator from sealing. You also don't have to worry about it fitting correctly. I don't think it will work for painting.
Half-face filter respirators are less expensive but don't protect your eyes, which can absorb fumes and toxic chemicals from dusts through all the capillaries on the eye surface.
A full-face filter respirator protects your eyes, but can be a bit uncomfortable, especially in the hot summer, and won't work with glasses. Okay for contacts, or you can buy corrective lenses that fit in the mask (a bit expensive).
For half-face and full face, it is important that it fits correctly, so you need the right size for your head, and one that will seal around your nose/jaw.
For woodworking, you want a P95 or P100 rated HEPA filter. These are for dusts only (not vapors). Can be a stand alone mask or an additional filter for a paint respirator.
For paint, you want one with an OSHA approved activated charcoal filter rated for OV (organic vapors). Those made of silicone rubber are usually more comfortable.
If you are planning to due some ammonia fuming, you want a filter that is also rated for ammonia fumes. A full-face model would be best for this.
3M makes a variety of the conventional filter type. When buying filters, make sure you get the correct ones to fit your model of respirator.
The cheap disposable dust masks may help some, but most often just fool you into thinking you are protected while providing a minimal reduction in what you are inhaling.
I didn't cover supplied air respirators.
Hope this helps

I'm in the same boat of needing to do something about the dust but more importantly my lungs. As I use the shop more I'm finding that it's quickly becoming covered in fine dust and that can't be good at all for my lungs. Then to make things worse I started reading about dust collection http://billpentz.com/woodworking/cyclone/index.cfm#index.cfm and am now more concerned.
I'd love to hear more experience on the trend air full face mask. It seems that I'm better off spending money on that for now until I can get a high quality dust collection system rather than making due with a cheaper 1.5 to 2 hp bag filter system.
I try to do my finishing outdoors if possible. Not the best situation but you have to work with what's available. Occasionally get that gnat that gets a little too close and have to sand him out.
The finer particles are the worst. Getting ready to build a downdraft table and have purchased one of those big gulp collectors and a cyclone for my DC. Best case scenario, the DC should probably be outside or not in an area where you can re-breathe the exhaust. Otherwise, you need HEPA filters for particulates.

I have a used Trend that has a new battery that I want to sell. If interested, I'll look up the price and sell it for 50%.
For those looking for supplied air type face masks like the Trend, I will post the following caution:
I did a search for the Trend mask, and saw a few other full-face supplied air respirators listed that appeared to be cheaper in price, and also touted for spray painting. Please realize these are designed to be attached to a breathing air source, and are not self contained like the Trend. Whatever you do, DO NOT hook one of these up to your shop air compressor. They require an air source that is certified to produce breathable air. Your shop air compressor has micro-particles of oil and possibly carbon monoxide in the air produced. No need to go into the hazards of CO, but the oil can coat your lungs and kill you (even if you are using an oil-water separator). It presents itself like a severe pneumonia, but unlike regular pneumonia, the oil cannot be removed or "cured" with antibiotics. (I believe the medical term is lymphotic interstitial pneumonia)
That said, if you do purchase the full system which does provide breathable air, it is probably the best protection, especially when painting. The downside other than cost is that you are dragging an air supply hose around with you as you work. Used with a hood instead of a mask, this type can be used by those who do not have sufficient pulmonary function to use a mask and by those wearing glasses.
I only post this because these systems have now dropped in price enough to be in the range of consideration for some of the readers of this forum, and the way some are designed, could easily be adapted to hook to a shop compressor. I don't want someone to save a buck and lose a life.

I would second the 3M facemask as very comfortable for extended use. Use with 2091 particulate filter which gives 99.97% filtering (NIOSH testing); there is also a 2097 filter version which adds some charcoal for nuisance vapors (non hazardous). We also used these in hospital around patients with infectious airborne diseases.

Joe,
Definitely get some good protection. Also I found that a large room air filter overhead cut down on the "fines" always floating around.
I used the Trend for a while, but found the weight of the battery/fan sitting on my head was too distracting. But then I was also dragging an oxygen hose around the shop. There is another, more expensive, option that I preferred. It's been a few years and two moves ago, so I can't identify the unit right now. I'll keep looking. Main feature is the battery and other heavy parts were in a belt pack, not on the helmet, and the seal around the face mask was better - at least for me. It was much more comfortable for long-term wear. I don't know how it worked with paints, but maybe I can get more info.
I remember that the vendor took my Trend in trade for something like 50% or more of its original cost.
I'll check more old records and see if I can't come up with more useful info for you, but definitely get some protection.
