Q: Uner normal conditions how often does the filter need to be replaced?

I have had the 250 for a few months and a slightly different model, 2 Airmega 100 for about a year. These allow you to change the charcoal filter. I vacuum the screen and filters monthly. With these cleanings and open windows with maybe 2 weeks of A/C in summer I would say the filters last a year. No wild fire smoke, a little second hand smoke from another apartment maybe once a night for 15 minutes in the winter in 1 room. To run at an acceptable sound level 24/7 over many days in heavy smoke conditions or summer I recommend getting MORE capacity than you need if you do anticipate wild fire or other smoke. I'm in a 700 sq ft apt divided into 1 large and one smaller area. I have the 250 and a100 for the larger section, and a 250 for the smaller section in anticipation of wildfire smoke years like 2020 when we had this for a few weeks. In summer I run at least one at level 2 all the time. I wouldn't be able to stand hearing them on setting 3 for more than a quick clear out, but on setting 2 they are okay should keep the air clean enough. I bought them slowly over a year's time. They do seem to also act as dehumidifiers - which may or may not be helpful depending on conditions where you live and time of year.

Q: Are the Airmega 250 filters the same as the Airmega 400 filters, i.e., interchangeable?

No, they are not interchangeable! The 250 & 400 filters are different sizes AND the 400 filters are sold in sets of two, because the 400/400S requires two filters (one on each side), whereas the 250/250S requires only one filter.
