Smoke Ventilation

[fjooeiks]

There is exhaust ventilation in the office above the table (where I smoke when I work) but it does not help. Next to the table is an air washer and the ionizer cleaner. it stinks of ozone and still doesn't help. Looking for a good air purifier. What do you use? What about this https://cleanhomeguide.com/best-air-purifier-for-smoke/ ? The topic is not for sayings like "quit smoking".

An air change is how many times the air enters and exits a room from the HVAC system in one hour.
Smoking rooms are usually designed for 15 - 20 air changes per hour.
1. Calculate the volume of the room (L’xW’xH’).
2. Multiply the volume of the room by the required room air changes.
3. Divide the answer by 60 minutes per Hour to find the required room CFM:

So, for instance, a 10' x 12' x 8'H room (960 cu ft) would require ([960 x 20] ÷ 60) a 320 CFM exhaust fan*, vented to the outside.

A “rule of thumb,” for designing negatively pressurized rooms (so that smoke from room A doesn’t infiltrate rm B), has been that a 10% differential between a room’s supply and exhaust (or return) airflow is adequate to prevent room air leakage to adjoining spaces.
In above room, supply air should be separately conditioned (heat/cool), and restricted to about 288 CFM (to maintain negative pressure).

* For instance, most residential bathroom fans are only rated from 50 to 110 CFM.

the best air filter i have found is nsa hepa filter. rids a normal sized room of diesel exhaust fumes in 8 min. i know as i have used that particular brand. i have a different one now and it is not as good at the diesel exhaust removal find em in ebay or amazon or just google nsa hepafilter. try to get new in box with extra filter changes.
best o luck with this. i have cough variant asthma..ionic things do nothing but exacerbate the issue. i LOVED my nsa filter. neighbor used to run his diesel for hours next to my boat in lost angels.... sucked and i was having difficulties, so i used the nsa with most awesome success.. and yes. i timed it---8 min until relief. was perfect. faster than finding and grabbing a nasty inhaler that gave me shakes for starting folks's ivs.... hahahahaha yes the filter worked.

Sounds about right.
The NSA 7100A is specified at 120CFM, and rated to 2400 - 3000 Cu Ft.
To single-pass (3 stage) filtre 2400 CF would take about 20 minutes (25min/3000cf).
A "normal sized" 12' x 10' x 8 Ft room (960CF) would take about 8 minutes, at 120cfm.

I don’t understand what your asking.
Nothing will remove the stench of cigarette smoke, so dilution is tried with moderate success.
I guess you could have a vent hood about like a welding station at your desk.
You work and smoke on a boat?
