Factory Disinfection Service

Safai's Disinfection Service goes beyond surface cleaning — our trained team follows a precise, step-by-step process designed around the real conditions of Dhaka homes. Whether it's the moisture that builds up during monsoon season, the persistent construction dust that settles in Dhaka's rapidly developing neighbourhoods, or a full pre-Eid deep disinfection, our method is equally thorough and reliable every single time.

Before any work begins, the team conducts a careful walkthrough of the space — noting high-risk zones, heavily trafficked areas, and whether the household includes children, elderly members, or pets. The correct chemical concentration and equipment are then selected accordingly. In Dhaka's large joint-family homes where many people share common spaces, this initial assessment is especially critical, because a one-size-fits-all approach simply does not deliver consistent protection across different environments.

The Disinfection Process, Step by Step

1. Conduct an on-site inspection and assess risk levels throughout the space
2. Select the appropriate chemical formula based on household members and pets present
3. Apply an even disinfectant mist across all rooms using an electrostatic sprayer
4. Perform manual focused sanitization on all high-touch points
5. Treat AC vents and enclosed areas with a fogging machine for deep penetration
6. Allow the specified dwell time to pass, then fully ventilate each room
7. Verify the checklist and hand over a digital service completion report

Once the service is complete, our team hands over a digital report detailing which areas were treated, which chemicals were used, and any recommendations for follow-up care. During the monsoon season, or if a household member has recently been ill, we also advise on the appropriate interval before the next session. Starting from BDT 2,500, this service can be booked for any Dhaka flat, office, or even an NRB family's vacant home that needs a thorough disinfection before residents move back in.

Safai's Disinfection Service does more than eliminate germs — it gives your home or office a visibly fresh, renewed appearance that regular wiping simply cannot achieve. Dhaka's heavy dust and monsoon humidity gradually build up a dull, grey film on walls, floors, and furniture surfaces. After a professional disinfection session, those surfaces look noticeably brighter, their original colour comes through, and the interior feels far more open and inviting. Whether you're preparing for Eid gatherings or expecting guests, this is the most effective way to get every corner of your space looking its best in a single booking.

In larger, joint-family households — where children, elders, and constant cooking are all part of daily life — masala stains, oil residue, and repeated hand contact leave everything from door handles to kitchen counters looking worn and tired. After a Safai service, these high-touch points don't just become germ-free; the built-up grease and staining is lifted away, restoring the original colour and finish of tiles, handles, and switchboards. Scheduling a professional disinfection at least once every six months meaningfully extends the lifespan of these surfaces, reducing the need for frequent repairs or replacements and saving real money over time.

A Better Business Impression and Genuine Peace of Mind — in One Service

For offices, clinics, and restaurants, a visibly clean environment directly shapes how clients and customers perceive your business. Walking into a fresh, spotless space builds immediate trust and confidence in your brand. For NRB families who visit Dhaka once a year and need a long-closed apartment made liveable fast, Safai's Disinfection Service is a complete ready-to-move-in solution — so the flat is clean, fresh-smelling, and fully usable from the moment they arrive. And for every customer, there's the simple peace of mind that comes from knowing every surface and every corner has been properly treated by trained professionals — without you having to lift a finger.

• Surfaces look visibly brighter and fresher — the dull film from Dhaka dust and monsoon humidity is cleared away
• Original finish restored on tiles, handles, and switchboards — fewer replacements, real cost savings
• Disinfecting every 6 months significantly extends the life of high-touch surfaces throughout the home
• Clients and customers form a positive first impression the moment they walk into your office or shop
• Complete pre-Eid or pre-event preparation for the whole space covered in a single booking
• Long-closed apartments made fully ready for NRB families returning home from abroad

The Safai disinfection team doesn't show up with a household spray bottle — we arrive fully equipped with professional-grade tools built for the job. Dhaka's monsoon humidity, pervasive road dust, and densely occupied apartments create the perfect conditions for bacteria, mold, and viruses to thrive. Tackling that effectively requires the right combination of machines and chemicals working together. That's why every Safai team carries ULV (Ultra-Low Volume) electric fogger machines, microfiber pad sets, and HEPA-filter vacuums — capable of capturing even microscopic airborne pathogen particles that ordinary cleaning misses entirely.

Our ULV fogger machines deliver a fine disinfectant mist deep into every corner of a room — beneath furniture, inside AC vents, and into the folds of curtains — reaching areas that hand-spraying simply cannot access. For high-touch surfaces like door handles, lift buttons, and bathroom taps, we deploy electrostatic sprayers that cause the chemical solution to wrap around and cling evenly to surfaces, extending its active protection for hours after application. In areas affected by stubborn stains or surface mold — a common issue in older Dhaka buildings during and after the monsoon season — our technicians use soft-bristle scrub brushes that clean deeply without scratching or damaging the underlying surface.

Our Chemicals: Safe, Certified & Genuinely Effective

At Safai, we don't just reach for the strongest chemical available — we use the right one. All of our disinfectants are WHO- and EPA-approved hospital-grade formulas proven effective against coronaviruses, E. coli, Salmonella, and common flu viruses. While our solutions are alcohol- or chlorine-based for maximum efficacy, once dry they leave no harmful residue, no harsh lingering odour, and pose no risk to children, elderly family members, or pets. Whether you're disinfecting your home ahead of Eid gatherings, preparing a property for returning NRB family members, or simply keeping a joint-family home protected year-round — our chemicals require only a 30–60 minute ventilation window before the space is fully safe for re-occupancy.

• ULV electric fogger machine — delivers fine disinfectant mist into every corner and hard-to-reach area
• Electrostatic sprayer — ensures even, long-lasting coverage across all high-touch surfaces
• HEPA-filter vacuum — captures airborne dust, allergens, and microscopic particles
• WHO & EPA-approved hospital-grade disinfectants — proven to eliminate viruses and bacteria
• Eco-certified, odour-free chemical formulas — safe for children, elderly, and pets
• Soft-bristle scrub brushes & microfiber pads — thorough deep cleaning without surface damage

A little preparation before your Disinfection Service booking goes a long way toward a faster and more thorough job. Clear surfaces like dining tables, display shelves, and countertops of valuables — jewellery, documents, electronic devices, and children's toys should all be stored safely away. If you have pets, keep them in a separate room or with a neighbour during the service, as the spray mist can be uncomfortable in an open space. In joint-family homes, let everyone know the schedule in advance to avoid repeated entries into rooms while work is in progress. Any open food on counters or outside the fridge should be covered or stored inside before the team arrives.

During the service, our team uses electric mist sprayers that produce a light hum and a fine haze — this is completely normal and expected. Depending on the size and condition of your space, the process typically takes one to three hours. During Dhaka's monsoon season, higher humidity means the mist may take a little longer to settle and dry, so factor in some extra waiting time. After the service is complete, keep doors and windows closed for at least 30 to 60 minutes to allow the disinfectant to work at full strength — then open everything up and let fresh air circulate freely throughout the space.

The First 24 Hours After Service and Long-Term Care

• Avoid mopping floors with a wet cloth for the first 24 hours after service — the disinfectant needs this time to fully bond and reach maximum effectiveness.
• Keep high-touch points like door handles, lift buttons, and stair railings sanitized regularly, especially when family members return from outside.
• If you're booking ahead of Eid or a family gathering, schedule the service at least 1–2 days before guests arrive so your home is completely ready and aired out.
• Masala stains and greasy kitchen surfaces can be spot-treated with a light all-purpose cleaner between professional sessions — this keeps build-up minimal and the next service more effective.
• In the monsoon season, if walls or ceilings show signs of dampness, pair your disinfection with good ventilation habits — otherwise mould and bacteria can return quickly.
• NRBs returning home or residents handing over a flat should book a disinfection session beforehand to make the space hygienic and move-in ready with minimal delay.

Making the results of a Disinfection Service last longer requires more than a single appointment — it calls for consistent habits in between. Dhaka's heavy dust pollution and monsoon humidity create conditions where germs and bacteria can return relatively quickly, which is why scheduling a session every three to six months is the ideal rhythm for most households, adjusted based on family size and daily footfall. In the time between professional sessions, regularly wiping down high-touch surfaces, leaving shoes at the door, and keeping the kitchen and bathrooms as dry as possible will help preserve the results of your service for as long as possible.

Dhaka consistently ranks among the world's most air-polluted cities, with AQI levels reaching hazardous thresholds especially during winter months. In this environment, indoor spaces accumulate dust, dust mites, and mold spores that place a direct burden on the respiratory system. Research shows that professional disinfection can reduce indoor bacterial Colony Forming Units (CFU) by up to 90%, bringing significant relief to family members — especially children and the elderly — who suffer from asthma, allergic rhinitis, or eczema.

Bangladesh's monsoon season and persistently high humidity (relative humidity of 80–95% between June and September) create near-ideal conditions for mold and mildew growth. Mold spores that accumulate in wall corners, bathroom ceilings, and air-conditioning vents become airborne and circulate throughout the home. Fungi such as Aspergillus and Cladosporium are known to cause chronic pulmonary inflammation with prolonged exposure. Safai's hospital-grade disinfectants rupture mold spore cell membranes and significantly inhibit re-growth on treated surfaces, keeping indoor air comparatively safer throughout the post-monsoon months.

Health Risks Reduced by Professional Disinfection

• Dust mite allergen reduction — Mite fecal matter and body fragments embedded in mattresses, sofas, and carpets are a leading trigger of sneezing, itchy eyes, and breathing difficulty in children; disinfection significantly lowers this allergen load.
• Bacterial and viral inactivation — High-touch points (door handles, switches, railings) harbor pathogens such as Staphylococcus, E. coli, and influenza viruses; hospital-grade disinfectant spray neutralizes them within 30 seconds of contact.
• Mold and mildew prevention — Mold spore concentrations during the monsoon can be 3–5 times higher than baseline; regular disinfection keeps concentrations in check, preventing the long-term pulmonary damage associated with chronic mold exposure.
• Pet dander and animal allergen reduction — In joint-family households where cats or dogs are kept, airborne pet dander is a known asthma trigger; environmental disinfection measurably lowers ambient allergen levels.
• Eczema and skin inflammation relief — Reducing exposure to environmental bacteria and fungi correlates with fewer flare-ups in children and adults diagnosed with atopic dermatitis or contact eczema.
• Improved indoor air quality — Clearing biofilm and mold from AC vents and curtains reduces the volume of contaminated particulates recirculated by air systems, easing the overall load on household members' respiratory tracts.

Many Dhaka families focus exclusively on visible cleanliness when preparing for Eid gatherings or welcoming NRB relatives back home — but the invisible microbial load remains. Apartments that have been closed for extended periods are particularly prone to elevated mold and bacterial counts, increasing the risk of respiratory infections and allergic reactions among returning occupants. Scheduling professional disinfection at least once every three months keeps indoor pathogen levels consistently low, reducing the cumulative strain on the immune systems of all household members, including young children and elderly grandparents in joint-family settings.
