My local costco has these units in store for $800 USD. Further down the isle they have oscillating tower fans for $30, and smart air filters for $100. I bought two pairs of each before winter. The fans are quiet, have plenty of control options, and non-volatle memory so you can use them with smart plugs. The air purifiers are 4 stage, with active charcoal and a long life (6 mo, 20$) hepa filter. They are wifi enabled, monitor and log air quality, and controllable from a phone. The purifiers should filter my bedroom's air once every 10 minutes, and ~15 min for my living room. This was all under 300$.
Edit: to answer your question, the regular dyson fans are great. They quietly and efficiently move air. Pointing one at a real air filter should really help the filter do its job. My issue is that dyson built a small filter into their fans and doubled the price.
