The Newest Must-Have Home Amenity for the Rich: Purified Air

Pollution, allergens and Covid have homeowners focusing on filtration systems and flexible designs to improve indoor air quality
Visitors to John Bautista and Pedro Salrach’s San Francisco home can’t get enough of the lap pool, sauna and movie theatre. But they also get a whiff of something else they value: clean air.
“The house smells new—and after two years it still smells new,” said Bautista, an attorney. “I know when I’m home because it smells clean and fresh.”

The six-bedroom home with seven bathrooms and two half-baths includes an elaborate air-filtration system meant to deal with the region’s varying air quality. The tightly sealed floor-to-ceiling windows and sliding doors offer hilltop views of the bay and access to the backyard without sacrificing air quality.
Bautista plans to further upgrade his system this year with the aim of filtering and recirculating indoor air rather than fresh outside air during periods of heavy pollution. Despite the home’s superior air quality, the family can still feel a difference on days when the outdoor air is filled with smoke. “We’ve suffered, as most people have in the Bay Area,” he said. “What we want to have is isolation.”
Developer Gregory Malin, who specialises in wellness-focused real estate, sold Bautista the home for $32 million, he said, plus an additional $5 million for fixtures and furnishings.

Luxury homeowners are known to splurge on sleek kitchens, custom decor and art, but they are increasingly turning their attention to something less visible. Forest-fire smoke, the pandemic and increased awareness of sensitivities to mould and other irritants are making their interior environment a priority.
Many are investing in complex systems and flexible designs that promise healthier indoor air but still include spaces, such as glass-enclosed rooms, that make being indoors feel natural.
Listings are increasingly touting pollution-fighting amenities to lure home buyers. In Santa Rosa, Calif., a 13-acre estate for sale at $15 million has a whole-home air purifier. This spring, the Dovecote building, under construction in Manhattan’s Harlem neighbourhood, will offer six, three-bedroom condos built to strict green and clean-air standards, starting at $1.5 million.
Malin, founder of Troon Pacific, a San Francisco-based developer of $15 million to $45 million properties that he calls healthy homes, said he focuses on the smallest details that can affect air quality. New tools allow for more-precise measurement of various particulate matter and carbon dioxide levels, he added. “Covid changed people’s perspective on connecting air quality to health, and the [wildfires] only enhanced that.”


His company’s newer homes have exhaust fans, tied to ventilation systems, in laundry rooms and under sinks, where there are various pollutants and harmful cleaning products, said Malin. Their garages have separate exhaust fans that go on long enough for three air exchanges after the door opens. Ionisation-based filtration systems also are included to eliminate airborne particles too tiny to see but hazardous when inhaled.
His homes also feature perforated piping with in-line fans to exhaust air from under slab foundations to keep contaminated soil vapours from entering the houses.
He said his company is considering building to the Living Building Challenge standard, in which homes have their own electricity, water and waste management. Demand is high for such standards, he said, including passive-home construction, where airtight homes are built using specific materials and energy-efficient systems that circulate highly filtered air. He said passive-home certification is costly, especially for big homes, and has limitations that some homeowners don’t want, like bulky windows. In the long run, however, he said eliminating most heating and cooling bills is probably worth it.


Clean air has become more of a talking point in homeownership, added Elliott Gall, an associate professor of mechanical and materials engineering who researches indoor-air quality at Portland State University.
While high-rises are often built to be airtight, there is a greater focus now on having windows that open while adding better filtration systems, he said. Units with outdoor access sometimes give homeowners another way to control the humidity and indoor air-pollution levels inside the home, he added.
To improve the air quality in her new Charleston, S.C., home, Caroline Smythe, 67, imported a hemp block covered in a mixture of lime and sand for the construction, rather than standard brick. Living in a high-humidity area means moisture can cause mould, said Smythe, whose 2,400-square-foot Lowcountry home was completed in 2023 for about $1 million, including $250,000 for the land.
Incorporating the new material allows the moisture to get absorbed in the walls and keeps humidity steady in the home. “It has very much an earthy feel,” said Smythe of her thick, soundproof walls.
Inside, the home’s two bedrooms and two offices have additional air-filtration elements, including stand-alone air filters for each bedroom. Smythe, a psychiatrist, chose a bamboo kitchen countertop and mineral-based wall paint to prevent any chemical off-gassing. “It makes a huge difference,” she said.
Homeowners have long tried to improve air quality. In the early 1900s, homes that let in fresh air were critical to good health, but by the 1950s some owners were trying to tame outdoor air pollution by focusing on better insulation. More recently, the pandemic made access to outdoor air essential, and turned the focus again to indoor-outdoor living.
Today’s picture is mixed. Climate change has made outdoor air quality less reliable, with the added problems of prolonged forest fires.
Many people are realising their indoor air quality is often compromised by a combination of poor indoor airflow, activities like cooking and cleaning, and outdoor pollutants that settle into confined spaces, said Gall. Homeowners now want better control over their wider living space, including modifiable systems that deal with both indoor and outdoor pollution, he added.

Jason Glatt, a commercial window contractor, and his wife, Lauren Glatt, a stay-at-home mom, of North Bethesda, Md., built a $2.5 million home that includes a children’s slide into a basement playroom, an attic-level cigar room and plenty of entertaining space.
The 11,000-square-foot home’s most striking feature, however, may be the five HVAC units tucked inside utility closets and other closed rooms, controlled by eight thermostats that regulate the air quality as well as temperature in each part of the home. Their $120,000 HVAC system also includes UV lights to prevent mould.
Seth Ballard, an architect who worked with the Glatt family, said individually controlled temperature zones and more return-air vents promote better air flow. Costs can be $100,000 to $200,000 for a 10,000- to 15,000-square-foot house. “They are choosing this over a kitchen countertop,” he said of homeowners in general.

Charlotte of the Upper West Side, a building in Manhattan that opened in 2023, has seven full-floor units, each with a private entrance. The building has airtight construction with enhanced insulation. Each unit has an independent heating-and-cooling system with fresh-air filtration directly into the home that isn’t shared with other spaces.
The system can achieve full air exchange 13 times a day in normal-use mode and more than 28 times a day in boost mode, said the building’s developer John Roe of the New York-based Roe Corp. The building uses louvers outside the windows to deflect the heat of the sun and cut energy use on summer days.
Roe, who lives in one of the building’s 3,570-square-foot, four bedroom, 4.5-bathroom homes, said the air-filtration system and strict passive-home construction added 15% to the building cost.
Three of the building’s units are on sale, from $8.35 million to $17 million.
He said there is little dust in the home, and he swears it now takes longer for his cut white hydrangeas to wilt.
Scotch whisky expert, luxury hospitality strategist and Keeper of the Quaich inductee Ross Blainey is bringing a new philosophy of luxury experiences to Citizen Kanebridge.
A restored 1860s Brisbane residence transformed by GRAYA has smashed Paddington’s house price record, selling for more than $12 million.
Scotch whisky expert, luxury hospitality strategist and Keeper of the Quaich inductee Ross Blainey is bringing a new philosophy of luxury experiences to Citizen Kanebridge.
From Scotch whisky and luxury retreats to fashion collaborations and world-class hospitality, Ross Blainey has spent years shaping high-end experiences around one idea: modern luxury is no longer just about what you own.
It is about access, connection and moments money alone cannot buy.
As Citizen Kanebridge continues to grow as one of Australia’s most sought-after private members’ clubs, Blainey, the club’s new Head of Membership, says the future lies in creating experiences members cannot find anywhere else.
“The ultimate memorable experiences are the money can’t buy moments,” Blainey said.
“The things that you can’t just put together anytime or any place. They make up something that is greater than the sum of its parts.”
On June 4, Blainey will bring that philosophy to life when he hosts an exclusive whisky evening for Citizen Kanebridge members at Sydney’s Royal Automobile Club of Australia.
Titled A Journey Through Whisky, the intimate event will see Blainey guide members through a curated selection of rare and unreleased whiskies drawn from his personal archive, alongside stories gathered across years working at the highest levels of the Scotch whisky world.
The evening will also include reflections on Blainey’s induction as a Keeper of the Quaich at Blair Castle in Scotland last year, one of the whisky industry’s rarest global honours.
Before joining Citizen Kanebridge, Blainey built a career spanning luxury hospitality, Scotch whisky, premium lifestyle brands and experiential events.
But he says one industry above all others shaped the way he thinks about people and community: Scotch whisky.
“At its core, at its heart and throughout its whole history, Scotch has been about sharing, enjoyment, telling stories, meeting people and generally having a good time,” he said.
“Whisky can be that shared moment of laughter, and it can also be a shared moment of just slowing down, taking stock and contemplating. These are so key to building community.”
Blainey’s deep involvement in the whisky world culminated in 2025 when he was inducted as a Keeper of the Quaich at Blair Castle, a recognition is reserved for a select group of individuals who have made an outstanding contribution to Scotch whisky internationally.
“I was inducted last year, 2025, an incredible honour,” he said.
“There were a couple of teary-eyed moments as I stood in Blair Castle, on historic ground, realising that this was a moment I would remember forever.”
Looking ahead, Blainey says Citizen Kanebridge will continue to focus on highly curated experiences, exclusive access, and bringing together like-minded members from Australia’s property, finance, and investment sectors.
“Our baseline of Car of the Year is already one of the most impressive events on the social calendar of Australia,” he said.
“My job is to find a way of raising the bar, taking things to the absolute top level for access, experiences and events.”
Blainey said the long-term goal was not simply to create another networking group or luxury club, but to build a community centred around meaningful relationships and unforgettable experiences.
“We provide the access, the money can’t buy memories, and we will be making those happen regularly,” he said.
“If we start with how amazing Car of the Year is and the only way is up, we are going to have some mind-blowing moments for our members.”
Another major influence on Blainey’s thinking came through his connection with world-famous New York restaurant Eleven Madison Park, once named the best restaurant in the world.
He says two concepts from the restaurant’s owners still shape the way he approaches luxury experiences today: “enlightened hospitality” and “unreasonable hospitality”.
“Enlightened hospitality is a way of doing business that looks at not just the product of what you serve, but how it makes people feel,” Blainey said.
“Unreasonable hospitality is more about striving for the absolute best all the time. If you’re going to do something, do it to an unreasonable level that blows everything else out of the water.”
It is a philosophy, he says, which aligns closely with where Citizen Kanebridge is heading next.
“That’s what we’re doing here with CK, taking members’ experiences to another level,” he said.
Blainey’s career has also included working with Glenfiddich as a Creative Collaborations Lead, where his role centred on bringing luxury experiences and partnerships to life through designers, chefs, artists and bartenders.
Among the projects were runway collaborations with leading Australian fashion designers, with pieces from the partnerships now housed inside Sydney’s Powerhouse Museum.
“My job was to find a creative way of bringing the brand to life,” he said.
“How do we make something that none of us could make on our own? Searching for the things that will resonate with people.”
Beyond whisky and events, Blainey also played a key role in building Blackbird Byron, the boutique Byron Bay hinterland retreat later recognised in Tatler’s Top 101 Hotels list.
The property, known for its dramatic views, minimalist architecture, and secluded atmosphere, helped shape his understanding of how luxury consumers are changing.
“I think I learned that people looking for luxury in hotels want memorable moments, considered design and the ability to get away from the hustle and bustle of modern life,” he said.
“To feel at home without being at home is important.”
More broadly, he believes today’s luxury consumers are increasingly driven by authenticity and emotional connection.
“For luxury consumers overall, I think it comes down to craft, story and connection,” he said.
“The product itself has to be impeccable, the story behind it builds your reason for looking at it, and then you need to make a genuine connection with people.”
