Are air purifiers a good option for keeping my apartment air cleaner?

I find the air in my apartment stale and I don't much like the smell. I don't think it's cooking smells and I don't smoke, I just think its the whole building (3 stories, 6 units and the hallway smells the same). I'm wondering if air purifiers really do work, thanks for any advice.
In the absence of anHRV, the most effective strategy for ensuringhealthy air at homeis to avoid introducing pollutants in the first place. This means, among other things,avoidingfurniture and other articles made of MDF (medium density fiberboard) and othermaterials that contain urea-formaldehyde. Read more here -

As for air purifiers, they don't always work as well as people hope. The way they operate is quite simple; air is drawn in and passes through a series of filters to remove contaminants, it is then ejected back into the room. They are usually equipped with a pre-filter for larger particles, an activated carbon filter and a HEPA filter (high efficiency particulate air filter).
空气净化器的局限性之一是它们只过滤悬浮颗粒，而室内的大部分污染物会沉积在表面(地板、家具等)，只有在受到干扰时才会在空气中传播。任何空气净化器都需要定期和严格的维护，以保持其有效性。
最后，便携式设备能够处理的空气体积非常有限，通常不超过10到20平方米的建筑面积。单一的便携式设备无法像集中式系统那样处理整个公寓或家庭的空气。
