We hope that you can remedy the situation so that we can move into a habitable home.Suggestions that we have to fix the issues:Hire a company to rip up the carpets, treat the subfloors, and replace the carpets, at least on the main level and on the stairs.Provide an air purifier as a start to remedying the smell.Replace the garbage disposal.Hire a plumber to fix the draining issue in the bathroom sink of the smaller bedroom.Fix the tiles in the upstairs bathroom so they no longer present a safety hazard.Replace or fix the screen doors.Fix the gap between the windows and the walls in the living room.Hire a professional company to treat the entire home for pests.

One option might be to explore adding air purifiers or filters directly into the system to help mitigate odors.

From talking to locals, there's a couple of issues than need to be addressed, some are the non-ecological practices that some of those developers have, unfortunately, our government profits from this investors and allows them to destroy manglers (which are the natural water purifying system of that area) dismantling hectares of mangroves and degraded the habitat of resident and migratory species burying animals alive.There's proof of fecal material floating beneath the city of Tulum, only 20% of the water is sent to the water treatment plant, there's no infrastructure for the exponential growth.The landfills in the middle of the jungle that is leaking hazardous pollutants into the freshwater system and that something that developers won't tell you.I love my country and it would be a disaster for everybody if this place ends up like some other great beaches around the world, that are completely ruined by greedy investors not following the rules.There's no urban or comprehensive master plan, and one of the risks is that Tulum will be like Playa del Carmen is today, overgrown and with environmental devastation.I will advise doing a lot of research before getting something in Tulum, different country, different rules, and practices.

I had a similar conversation with a tenant, complaining to me that his allergies were worse...I was like, well, this house had brand new carpeting throughout when you moved in, but most people with allergies don't chose a house that is carpet throughout, and live with 2 dogs who shed so much they will clog the air filter in a month, and told him about plug-in  air purifiers, since the furnace isn't designed to clean the air, only to heat it, and those high rated filters are bad for HVAC systems according to any HVAC guy you talk to.

But hopefully an air purifier can help too.

I have a side-hustle representing a revolutionary device that:  * Restores and purifies the body by assisting the lymphatic system and helps detoxify* Prepares and supports your muscles for pre and post workouts* Reduces inflammation, reduces swelling, faster healing* Revitalizes the body with body contouring and cellulite deduction* Enhanced sleep and mental clarity...and a lot moreThis device is connected to an app uses AI to track results and progress. 

He mentioned that an air purifier would help with allergies.   

My background is in ecological design, which you can find out more about in my profile, but in short it means I design and help create abundant edible landscapes that not only grow healthy food, but also enhance the ecology by purifying water, providing habitat for wildlife, and actually sequestering Carbon dioxide from the atmosphere in soil and plants.I have much gratitude to the creators of this space for creating something that is truly inspiring and brings people together.  

We finally sealed all the walls, ceilings and floors with Zessner odor killing sealer which helped a lot, purchased an air purifier, and kept the house open as much as we could. 

Also @Tim Porsche spoke of an ozone generator, also consider an Hepa filter air purifier.
